Two neutral bodies of masses $m_1$ and $m_2$ are kept at a distance of r cm from one another in a vacuum medium. A gravitational force F acts between the two bodies. The entire set-up is then transferred, as it is, to a water medium. The force between the bodies is then $F_w$. The ratio of F to $F_w$ is:

Two particles, one heavy and the other light, placed at $50\text{ cm}$ from each other, are under the influence of gravitational force of one another. If mass of the heavier particle is $4\text{ kg}$ and its acceleration under the influence of gravitational force is $5\times10^{-10}\text{ m s}^{-2}$, find the mass of the lighter particle.

If the radius of earth were to shrink by two percent, its mass remaining the same, the acceleration due to gravity on the earth's surface would

Two spherical planets \( P \) and \( Q \) have the same uniform density \( \rho \), and masses \( M_P \) and \( M_Q \), and surface areas \( A \) and \( 4A \) respectively. Another spherical planet \( R \) also has the same uniform density \( \rho \), and its mass is \( M_P + M_Q \). The escape velocities from these planets is

The value of universal gravitational constant was first determined by
