Question
The expression E=−dvdr implies, that electric field is in that direction in whichincrease in potential is steepest.decrease in potential is steepest.change in potential is minimum.None of these
Solution
The expression E = -dv/dr implies that the electric field is in the direction in which the decrease in potential is steepest. This is because the negative sign indicates the direction of the electric field is opposite to the direction of increasing potential, hence it points towards the direction of steepest decrease in potential.
