Question

14. The electric potential V at any point O(x, y, z all in metres) in
space is given by V = 4x2 V. The electric field at the point
(1 m, 0,2m) in volt metre-lis
(a) 8 along negative X-axis (b) 8 along positive X-axis
(c) 16 along negative X-axis (d) 16 along positive Z-axis
16 The clectric potential V is given as a function of distancer​

Answer 1

Explanation:

differentiate the potential while to get electric field and integrate electric field to get potential wrt distance but negative sign should be there in both cases

hope this helps you
