Consider the situation shown in figure. The width of each plate is b. The capacitor plates are rigidly clamped in the laboratory and connected to a battery of emf V. All surface are frictionless. Calculate the extension in the spring in equilibrium (spring is nonconducting)
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Sol.
Potential energy = 
(C 1 + C 2 ) V 2
= 
V 2
F = – 
= – 
F = 
V 2
where, 
= 
{1 – K}
F = 
at equilibrium, F = K s x
x = 
=
