Multiple choice

Two metal plates of area 0.01 m2 carries a charge of 100 μC, are separated by a distance of 1 cm. What is the force on metal plates having potential 3 x 106 V?

  1. 3 x 108 V/m

  2. 3 x 104 Vm

  3. 3 x 10-8 m/V

  4. 3 x 106 Vm

  5. 3 x 106 V/m

A Correct answer
Explanation

Distance between the plates - d = 1cm =1×10-2 m We know that, Strength of electric field (E) = Potential(V )/Distance( d) E = 3  x 106/10-2 = 3 x 108 V/m Which is more than dielectric strength of air, so it is not possible.
