In a uniform electric fieled, the potential is ` 10V` at the origin of coordinates , and ` 8 V` at each of the points (1, 0, 0), (0, 1, 0) and (0, 0, 1). The potential at the point (1, 1,1 ) will be .A. ` 0`B. ` 4 V`C. ` v`D. ` 1 0V` |
Answer» Correct Answer - B ` vec E = 2 hat I + 2 har j + 2 hat k` ` dV =- vec E . Vec (dr)` ` V-10 =- (D_x dx+E_y dy + E_z dz)` ` V= 10 =- (2 +2 +2) rArr V =4` volt . |
