Topic: Electrostatic potential and capacitance
Time :
1. If potential (in volts) in a region is expressed as V (x, y, z) = 6xy - y + 2yz, the electric field (in N/C) at point (1, 1, 0) is
(1). \(-\left(2\hat{i}+3\hat{j}+\hat{k}\right)\)
(2). \(-\left(6\hat{i}+9\hat{j}+\hat{k}\right)\)
(3). \(-\left(3\hat{i}+5\hat{j}+3\hat{k}\right)\)
(4). \(-\left(6\hat{i}+5\hat{j}+2\hat{k}\right)\)
