Question
Q A UNIFORM SPHERICAL SHELL GRADUALLY SHRINKS MAINTAING ITS SHAPE. THE GRAVITATn POTENTIAL AT THE CENTRE WILL DECREASE. Y DOESN'T IT SHD REMAIN CONST. =?
Joshi sir comment
Formula for gravitational potential at centre is -3/2 GM/R so if R will decrease V will increse numerically but - is present so decreases
