Statement-1: For the calculation of gravitational force between any two uniform spherical shells, they can always be replaced by particles of same mass placed at respective centres.
Statement-2: Gravitational field of a uniform spherical shell out side it is same as that of particle of same mass placed at its centre of mass.
A. Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
B. Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.
C. Statement-1 is true, statement-2 is false.
D. Statement -1 is false, statement -2 is true.

How is the gravitational force between two point masses affected when they are dipped in water keeping the separation between them the same?

By Universal law of gravitation, F = \(\frac{Gm_1m_2}{r^2}\) The force acting between two point masses m1 and m2, is independent of the nature of medium between them. Therefore, Gravitational force acting between two...
