Question

QUESTION 14 The figure shows the lectric potential at the locations in a uniforme Attich poster .V. V The electric potential has different values at all five presented points. V = V = Ve=V Vo = Vo Electric Potential has the same value at all points of uniform electric field.

Answer 1

Answer is option C.

In a constant Electric field,

If move along the Electric field direction potential decreases that is potential difference is negative,

$v1-v2=E*(a2-a1)$

as, $dv=- \int_{a1}^{a2}E.dr$

so V_a,V_b,V_c,V_e will have different potentials ,but V_b,V_dare on same vertical line

If we move perpendicular to the Electric field there will be no potential difference as E and dr dot product will become zero.

as V_b,V_d are on perpendicular line to Electric field potentials at that points are same

A) As Vb=Vd it is wrong

B) They have different potentials

C) It is correct Vb=Vd

D) 4 points have different potentials
