Q8.14Multiple correct
Supposing Newton’s law of gravitation for gravitation forces F1 and F2 between two masses m1 and m2 at positions r1 and r2 read r m m F1 = – F2 = – 123 GM 0 2 1 2 2 where M0 is a constant of dimension r12 M0 of mass, r12 = r1 – r2 and n is a number. In such a case,
- (a)the acceleration due to gravity on earth will be different for different objects.
- (b)none of the three laws of Kepler will be valid.
- (c)only the third law will become invalid.
- (d)for n negative, an object lighter than water will sink in water.
