Consider a Gaussian sphere of radius rian
[
a angle r

# 33. The region between two concentric spheres of radii 'a' and 'b', respectively (see figure), has volume charge density p=-, where A is a constant and r is the distance from the centre. At the centre of the spheres T ng is a point charge Q. The value of A such that the electric field in the region between the spheres will be constant, is :- (JEE Mains - 2016] OIBOAG-AKLEEAdvanced Spy Untolo 20 (3) 27(b? – a?) (4) T(a? – b?) 2īta
