Question

A + 3.0 nC charge Q is initially at rest at a distance of r1 = 10 cm from a + 5.0 nC charge q fixed at the origin.

A + 3.0 nC charge Q is initially at rest at a distance of r₁ = 10 cm from a + 5.0 nC charge q fixed at the origin. The charge Q is moved away from q to a new position at r₂ = 15 cm. In this work done by the field is :

(a) 1.29 x 10^-5J

(b) 3.6 x 10⁵ J

(c) -4.5 x 10^-7 J

(d) 4.5 x 10^-7 J
