Let V and E denote the gravitational potential and gravitational field respectively at a point due to certain uniform mass distribution described in four different situations of column-I. Assume the gravitational potential at infinity to be zero. The value of (E ) and (V ) are given in column-II. Match the statement in column-I with results in column-II. ( array |c|l|c|l| & Column I & & Column II A. & At centre of th
