Question

An object with a charge of -3.7 μC and a mass of 4.7×10−2 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight

. Find the magnitude of the electric field.

Answer #1

An object with a charge of -2.7 μC and a mass of 4.7×10−2 kg
experiences an upward electric force, due to a uniform electric
field, equal in magnitude to its weight.
Find the magnitude of the electric field.
If the electric charge on the object is doubled while
its mass remains the same, find the direction and magnitude of its
acceleration.

a) A particle with a charge of -4.0 μC and a mass of 4.9 x
10-6 kg is released from rest at point A and accelerates
toward point B, arriving there with a speed of 83 m/s. The only
force acting on the particle is the electric force. What is the
potential difference VB -
VA between A and B? If VB
is greater than VA, then give the answer as a
positive number. If VB is less than
VA,...

A negative charge of q =
-3.1 × 10-17C and m = 4.7 × 10-26 kg
enters a magnetic field B = 0.55 T with initial velocity
v = 230 m/s, as shown in the figure. The magnetic field
points into the screen.
q = -3.1 × 10-17C
m = 4.7 × 10-26 kg

7) A charge of -9 micro-coulombs with a mass of 11 kg is placed
on a horizontal surface. A uniform electric field is applied either
in the +y or -y direction (perpendicular to the surface). In order
to lift the charge off the surface (i.e. the normal force becomes
zero) what does the minimum magnitude of the field need to be and
in what direction does it need to be applied? Answer in 106 N/C as
in previous problems and...

Three point charges are placed on the x-axis. A charge of +2.0

An
object with a mass of 10.0 kg is falling under the effect of
gravity near the earth's surface with negligible air resistance.
There is a force of 55 N pushing it to the left (you can pretend
that this force is due to wind if that helps). What is the
magnitude and direction of the total force felt by the object?
Note: if the magnitude is greater than 140 N then you have done
this problem wrong and you...
