Question

An electric field E → = 10 x i ^ N C - 1 exists in space where x is measured in metre. Considering the potential at 10 m , 20 m to be zero, the potential at the origin is, 1000 V, 100 V, 375 V, 500 V

MARKS App · Accepted Answer

d V = – E → . d r → If V 0 is the potential at the origin, then ∫ 0 V 0 d V = - ∫ 10 0 E d x ⇒ V 0 = 10 10 2 2 = 500 V
