Explanation:
Given data:
first case
Distance of electric field from center of sphere is r_1 <R
Electric field at r_1< R
second case
Distance of electric field from centre of sphere is r_1 < 2R
Electric field at r_1< 2R
so, we have
Answer:
Explanation:
Given that the force of the particle is,
Now it can be further written as
Now the initial conditions are v=1 at t=0.
So,
Now the velocity will become.
And,
And, another initial condition is x=0 at t=0
Now,
