1.	The gravitational potential changes uniformly from-20 J /kg to - 40 J/kg as one moves along X-axis from x =- 1 m to x = + 1 m . Mark the correct statement about gravitational field intensity of origin.
Answer» The gravitational field intensity ATX = 0 must be equal to 10 N/kg. The gravitational field intensity atx = 0 may be equal to 10 N/kg. The gravitational field intensity atx = 0 may be greater THAN10 N/kg. The gravitational field intensity atx = 0 must not be LESS than10 N/kg. Answer :B::C::D
