    Choose the correct alternative : (a) If the gravitational potential energy of two mass points infinite distance away is taken to be zero, the gravitational potential energy of a galaxy is (positive /negative/zero). (b) The universe on the large is shaped by (gravitational/electromagentic) forces, on the atomic scale by (gravitational/electromagnetic) forces, on the nuclear scale by (gravitational/electromagnetic/strongnuclear) forces.

    Statement I: The magnitude of the gravitational potential at the surface of solid sphere is less than that of the centre of sphere. Statement II: Due to the solid sphere, the gravitational potential is the same within the sphere.

    Assertion : When two masses come closer, their gravitaional potential energy decreases. Reason : In moving attract each other.

    STATEMENT-1 : When two isolated charged metal spheres are touched with each other potential energy of system may decrease. and STATEMENT-2 : There may be transfer of charge from one to other after touching.
