Aproton is acted on by an uniform electric field of magnitude 183 n/c pointing in the positive y-direction. the particle is initially at rest. (a) in what direction will the charge move?
(b) determine the work done by the electric field when the particle has moved through a distance of 4.15 cm from its initial position.
(c) determine the change in electric potential energy of the charged particle.
(d) determine the speed of the charged particle.

Part a)

charge will move initially in +Y direction

Part b)

Part c)

Part d)

Explanation:

Part a)

Since electric field is in +Y direction so positive charge will move in the same direction

So charge will move initially in +Y direction

Part b)

Force due to electric field on the charge is given as

now work done to move it by 4.15 cm is given as

Part c)

As we know that work done by conservative force is negative change in potential energy

so we will have

Part d)

Work done by electric field = change in kinetic energy of the charge particle

here we have

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
