1.	A spherically symmetric non-rotating body of radius R has varying volume density given by rho = rho_(0)r where rho_(0) is a positive constant and r is distance from centre. For this situation mark the correct statement (s ) with respect to gravitational field intensity.
Answer» It is definitely zero at CENTRE it MAY be non zero at centre as one moves out (radially) from centre it first INCREASES non-linearly acquires maximum value at SURFACE and then decreases non-linearly both (a) and (C ) are correct Answer :B
