A point charge is placed at the centre of a hollow conducting sphere of internal radius ' and outer radius '2r. The ratio of the surface charge density of the inner surface to that of the outer surface will be ___________ .

Answer»


SOLUTION :Surface charge density on INNER surface `sigma_(1) = (q)/(4pir^(2)).`and that on the outer surface `sigma_(2)= (q)/(4pi(2r)^(2))=(q)/(16pir^(2))IMPLIES (sigma_(1))/(sigma_(2))=(4)/(1)`
