Answer 1

hope it will help you.

Answer 2

Answer:

acceleration of the charged particle If the direction of the electric field between the plate is reversed is 2g.

Explanation:

Given,

A charged particle of mass m is kept in equilibrium in the electric field between the plates of milikan oil drop experiment. the direction of the electric field between the plate is reversed.

To find: acceleration of the charged particle if the direction of the electric field between the plate is reversed..

Solution:

Mass of charged particle = m

Suppose the charge of the particle be q and intensity of electric field in between plates = E.

So, During the equilibrium,

mg = qE  ...(i)

But, Since the direction of the electric field between the plate is reversed,

hence, ma = mg + qE

from (i):  ma = 2mg

or,  a = 2g

Therefore, acceleration of the charged particle If the direction of the electric field between the plate is reversed is 2g.
