Three concentric spherical metallic shells JC, Y and Z of radius a, b and c respectively [a < b < c] have surface charge densities σ, -σ and σ, respectively. The shells X and Z are at same potential. If the radii of X & Y are 2 cm and 3 cm, respectively. The radius of shell Z is_____cm.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(5)
The charges on the spheres are
It is given that Vx = Vz
So,
c = a + b = 2cm + 3cm = 5cm
