Question

Two charged objects 1 and 2 are held at a distance *r*
apart. Object 1 has mass *m* and charge +3*q*, and
object 2 has mass 2*m* and charge +*q*. The objects
are released from rest. Assume that the only force exerted on
either object is the electric force exerted by the other
object.

**Part B**

When the objects are at a distance 4*r* apart, what is
the speed of object 1?

**Part C**

When the objects are at a distance 4*r* apart, what is
the speed of object 2?

**Part D**

When the objects are very far apart, what is the speed of object 1?

**Part E**

When the objects are very far apart, what is the speed of object 2?

Answer #1

Two charged objects sit on the x-axis. The first object, with
charge q1 = 16 nC, sits at the origin while the second
object, with charge q2 = -36 nC sits at 2.5
cm.
a) Find the force exerted by charge q1 on charge
q2. Give both the magnitude and the direction of the
force.
b) Find the magnitude and direction of the electric field at the
position x = 1 cm.

two
small, positively charged spheres with charges and masses are
initially held stationary a distance d=3.13x10^-3 m apart. they are
then bith released.
what is the final speed of charge Q1
(disregard this queation—-already solved)

Two
small charged objects attract each other with a force F when
separated by a distance d/2. If the charge on each object is
reduced to one-fourth of its original value and the distance
between them is reduced to d/4 the force in the second case is
related the force in the first case by :

A charge of 5 m(micro)C is held fixed at the origin. A second
charge of 5 m(micro)C is released from rest at the position (1m,
2m)
a) if the mass of the second charge is 2g what is its speed when
it moves infinitely far from the origin?
b) at what distance from the origin does the second charge
attain half the speed it will have at infinity?

Two equally charged particles, held 4.0 × 10-3 m
apart, are released from rest. The initial acceleration of the
first particle is observed to be 7.3 m/s2 and that of
the second to be 8.4 m/s2. If the mass of the first
particle is 8.5 × 10-7 kg, what are (a)
the mass of the second particle and (b) the
magnitude of the charge of each particle?

Two equally charged particles, held 4.0 × 10-3 m
apart, are released from rest. The initial acceleration of the
first particle is observed to be 5.5 m/s2 and that of
the second to be 9.0 m/s2. If the mass of the first
particle is 7.8 × 10-7 kg, what are (a)
the mass of the second particle and (b) the
magnitude of the charge of each particle?

Two particles which have the same magnitude charge but opposite
sign are held r = 7 nm apart. Particle I is then released
while Particle II is held steady; the released particle has a mass
of 8.72 × 10-23 kg. Particle I's speed is 110 km/s when
it is 0.74r away from Particle II.
1. What is the magnitude of the charge on one
of the particles?
2. If the particles are still initially held 7 nm apart but
both...

1. Positively charged objects have gained protons?
2. A charged object can only attract other charged objects?

independent of the distance between them?
4. Static charges are produced through friction?
5. What is the difference between charging by contact and
charging by induction?
6. Charges produced by induction always,.. A.) attract or B.)
Repel?
7. Charges produced by contact always...A.) attract or B.)
Repel?

Two equally charged particles are
held 4.1 ✕ 10−3 m apart and
then released from rest. The initial acceleration of the first
particle is observed to be 5.5 m/s2 and
that of the second to be 9.4 m/s2. The
mass of the first particle
is 6.3 ✕ 10−7 kg.
(a) What is the mass of the second
particle?
kg
(b) What is the magnitude of the charge of each
particle?
C

Two objects are at rest on a frictionless surface. Object 1 has
a greater mass than object 2. When a force is applied to object 1,
it accelerates for a time interval ∆t. The force is removed from
object 1 and is applied to object 2. After object 2 has accelerated
for the same time interval ∆t, which statements are true?
(a) p1 < p2
(b) p1 = p2
(c) p1 > p2
(d) KE1 < KE2
(e) KE1 =...
