Question

(ix) The electric potential at a point on the axis of a water molecule
of electric dipole of moment 6.25 x 10-30 C.m if the point is
1 nm from the centre of the dipole is
(1)
(a) 5.625 x 10-11 V (b) 5.625 x 10-3 V
(c) 56.25 x 10-3 V
(d) 5.625 x 10-12 V.​

Answer 1

Answer:

(c)

Explanation:

V = KP/r²

K = 9×10⁹Nm²/c²

r = 1nm = 1/10⁹m
