Class 12 Physics Chapter 2 Electrostatic Potential & Capacitance Important Questions | Part 1

The electric potential is V=(x^(2)-2x) . What is the electric field strength at x=1?

7S is a solid neutral conducting sphere. A point charge q of 1 × 10–6 C is placed at point A. C is the centre of sphere and AB is a tangent. BC = 3m and AB = 4m. (1) The electric potential of the conductor is 1.8 kV (2) The electric potential of the conductor is 2.25 kV (3) The electric potential at B due to induced charges on the sphere is – 0.45 kV (4) The electric potential at B due to induced charges on the sphere is 0.45 kV

4Statement - 1 : The electric potential and the electric field intensity at the centre of a square having four fixed point charges at their vertices as shown in figure are zero. Statement - 2 : If electric potential at a point is zero then the magnitude of electric field at that point must be zero.

Statement-1 : Electric potential of earth is taken to be zero as a reference. Statement-2 : The electric field produced by earth in surrounding space is zero.
