Grade 12Electric Current
The charge per unit lenth on a square wire frame is constant in magnitude on two of its sides. A pair of adjacent sides are positively charged and the other pair is negatively charged. Then
a) at the center E is 0 but potential is not 0
b)at the center E is not zero but potential is 0
c)at the center E as well as potential is 0
d)at the center E as well as potential is not 0
