Acceleration due to gravity increases/decreases with increasing depth. (assume the earth to be a sphere of uniform density).
Which of the following quantities remain constant in a planetary motion (consider elliptical orbits) as seen from the sun?
Two small bodies of masses 10 kg and 20 kg are kept a distance 1.0 m apart and released. Assuming that only mutual gravitational forces are acting, find the speeds of the particles when the separation decreases to 0.5 m.
How will the force of gravitation between two objects change if the distance between them is:
Halved
All objects in the universe attract each other along the line joining their________.
Name and state the action and reaction in the following case:
Hammering a nail.
The gravitational force between two bodies is directly proportional to the product of the masses of those bodies and is _______ of the distance between them.
Mahendra and Virat are sitting at a distance of 1 m from each other.Their masses are 75 kg and 80 kg respectively. What is the gravitational force between them? (G = 6.67 × 10-11 Nm2/kg2)
Different points in earth are at slightly different distances from the sun and hence experience different forces due to gravitation. For a rigid body, we know that if various forces act at various points in it, the resultant motion is as if a net force acts on the c.m. (centre of mass) causing translation and a net torque at the c.m. causing rotation around an axis through the c.m. For the earth-sun system (approximating the earth as a uniform density sphere).
How is the gravitational force between two point masses affected when they are dipped in water keeping the separation between them the same?
