Question

A proton (m = 1.67 x 10^{-27} kg) is placed a distance y
above a long, horizontal wire of linear charge density λ. The
proton is then released from rest. If the magnitude of the initial
acceleration of the proton is 0.52 x 10^{+7}
m/s^{2,} what is the value of λ (in C/m)? Take y =
40cm.

Answer #1

A proton (m = 1.67 x 10^2 kg) is placed a distance x to the left
from a long, vertical wire of
linear charge density A. The proton is then released from rest. If
the magnitude of the initial
acceleration of the proton is 0.52 x 10^7 m/s2 what is the value of
A (in C/m)? Take x = 40cm.
K= 9* 10^9 N.m2.C2, E= 8.85 x 10^-12

A proton (m = 1.87 10-7kg) is placed a distance y
above a long, horizontal wire of linear charge density. The proton
is then released from rest. If the magnitude of the initial
occaration of the proton is 3.4x107m / s what is the value of y (in
m)? Take AB.8x10 cm K = 9x 10+ N.mc-.to -8.85 x 102 cm

A proton (m = 1.67 x 10-27 kg) travels a distance of 4.3 cm
parallel to a uniform electric field 2.3 x105 V/m between the
plates shown in the figure. If the initial velocity is 1.9 x 105
m/s, find the magnitude of its final velocity in m/s. (* Ignore
gravity)

An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m2 =
1.67 x10-27 kg) attract each other via an electrical force. Suppose
that an electron and a proton are released from rest with an
initial separation d = 3.50 x 10-6 m. When their separation has
decreased to 1.40 x 10-6 m, what is the ratio of (a) the electron's
linear momentum magnitude to the proton's linear momentum
magnitude, (b) the electron's speed to the proton's...

A proton (q = 1.6 X 10-19 C, m = 1.67 X 10-27 kg) moving with
constant velocity enters a region containing a constant magnetic
field that is directed along the z-axis at (x,y) = (0,0) as shown.
The magnetic field extends for a distance D = 0.75 m in the
x-direction. The proton leaves the field having a velocity vector
(vx, vy) = (3.9 X 105 m/s, 1.9 X 105 m/s).
1)What is v, the magnitude of the velocity...

A beam of protons (proton mass is 1.67 x 10 - 27 kg) moves at 3
x 10 5 m/s through a uniform magnetic field with magnitude 2 T.
The magnetic field has exactly equal components along the positive
y and negative x axes and no component along the z axis. The
velocity of each proton lies in the xz- plane at an angle of 30
0 to the z- axis.
(a) Write the magnetic field B and the velocity...

Chapter 7, Problem 1. A proton (mass m = 1.67 × 10-27 kg) is
being accelerated along a straight line at 5.40 × 1013 m/s2 in a
machine. If the proton has an initial speed of 6.20 × 105 m/s and
travels 2.40 cm, what then is (a) its speed and (b) the increase in
its kinetic energy?

A proton (e = 1.60 X 10-19 C and m = 1.67
X 10-27 kg) is traveling at 90.0° with respect to the
direction of a magnetic field of strength 4.50 mT experiences a
magnetic forceof 7.50 X 10-17 N. The
proton's kinetic energy is:

(1) A proton (mass m = 1.67 ✕ 10-27 kg) is
being accelerated along a straight line at 3.4 ✕ 1015
m/s2 in a machine. The proton has an initial speed of
2.4 ✕ 107 m/s and travels 4.1 cm.
(a) What is its speed? (Give your answer to at least four
significant figures.)
(b) What is the increase in its kinetic energy?
(2) A helicopter lifts a 82 kg astronaut 20 m vertically from
the ocean by means of...

The mass of a proton, mp, is estimated to be 1.67×10^−27 kg, and
the mass of an electron, me, is estimated to be 9.109 ×10^−31 kg.
How many protons would it take to make a mass of 1g? 1kg? 1kg? How
many electrons would it take to make a mass of 1g? 1kg?
