An electric field E→=Axi^ exists in the space, where A =10 V/m2. Consider the potential at (10 m, 20 m) to be zero. The potential (in V) at the origin is ______

Figure shows the situation described in question. Here BC is the equipotential line so we can useVC=VB=0If V0 be the potential at the origin, we can use V0−VB=∫AB Edx=∫010 Axdx⇒ V0−0=Ax22010=10×1022=500V
