The electric ...

Question

The electric potential V at any point in space is given V=20x3 volt, where x is in meter. Calculate the electric intensity at point P(1,0,2).

Open in App

Solution

we know that the following relation exists between electric field (E) and potential (V)

E = -dV/dx

here

V = 20x³ volts

so,

E = d(20x³)/dx

or

E = 60x²

here

x = 1

thus,

E = 60.(1)² = 60 N/C
