Question

As shown in the figure, the electric field lines on
the right have twice the separation of those on the
left. If a charge particle takes time t to move a
distance x in left region, then how much time will
it take to travel same distance in right side region?
(1) t/2
(2) t
(4) 2t
(3) √2t​

Answer 1

The time taken by the charge is T = √ 2 t

Explanation:

Case I:

T = 2π √ ml / qE

T = 2π √  m x 2d / qE   ----(1)

Case II:

T =  2π √ m x qd / qE ------(2)

Comparing equation 1 and 2

T = √ 2 T

Thus the time taken by the charge is T = √ 2 t
