The electric potential V at any point x, y, z in space is given by V = 4 x^2 V. The electric field at the point (1, 0, 2) is_________ V m^(-1).

Answer»

SOLUTION :`-8hati, VEC E =- (dV)/(dr)HATR = -[(delV)/(delx)hati + (delV)/(dely)HATJ+(delV)/(delz)hatk] = (-del)/(delx) (4 x^2)hati` and at point (1, 0 , 2) we have `vec E = -8 hati`
