The mass of two bodies are doubled and the distance is halved, how will the gravitational force change?

The masses of two bodies are m_1 and m_2 the distance between them is d. What is the gravitational force between them?

If the distance between 2 objects is doubled then how will the gravitational force between them change?

Give two characteristics of gravitational force.

A rocket is fired from the earth towards the sun. At what distance form the earth's centre is the gravitational force on the rocket zero? Mass of the sun = 2 xx 10^20 kg and mass of earth = 6 xx 10^24 kg and orbital radius 1.5 xx 10^-8 km.

In a Young's double slit experiment, the distance between slit is halfed and distance of screen is made three times. How will the frige width change?

A parallel plate capacitor of capacity 100 muF is charged to 500 V. If the distance between the plates is halved, what will be the new potential difference and the change of stored energy?

If somehow the distance between the sun and the earth is doubled, the gravitational force between them will became

How can the velocity of a body be changed?

The electric field produced due to an electron is just sufficient to balance the gravitational force on another electron located above the first. Find the distance between the two electrons.

A spring has a mass m suspended from it. If the spring is cut in half and same mass is suspended, from one of the halves, will the frequency of vibration is changed ?
