Gravitation

Speaker(Fat man):Hm...the force with which I attract Raju(slim man) must be much greater than the force with which Raju attracts me.

• I agree with the speaker

• I do not agree with the speaker

The force that causes this acceleration and keeps the body moving along the circular path is acting towards the centre.

This force is called---------------

• Centripetal force

• Gravitational force

• Magnetic force

• Circular force.

In the absence of the centripetal force, the stone flies off along-----------

• the circular path itself.

• a curved path.

• a straight line.

• the centre.

The earth do not fall towards an apple because-------

• For a given force, the acceleration is inversely proportional to the mass of the object.

• For a given force, the acceleration is directly proportional to the mass of the object.

Every object in the universe attracts every

other object with a force which is proportional

to the product of their ------- and inversely

proportional to the ---------

• masses, distance between them.

• masses,square of the distance between them.

• distance between them,masses

• square of the distance between them,masses

If M=m=1 kg and d= 1 m, Then the gravitational force between M and m is------------------

• 6.673X10^-11 N

• 6.673X10^-11 Nm²kg^-2

• 1 N

• None of the above

Gravitational force obeys inverse square law.

• True

• False

Mass of the earth is---------------

• 6X10²⁴ kg

• 6.4X10²⁰kg

• 24X10⁶ kg

• 6.673X10^-11 kg

Inverse square law was formulated by----------

• Kepler

• Galileo

• Newton

• Pascal

The law is universal in the sense that

it is applicable to --------

• all bodies, whether the bodies are big or small

• all bodies,whether they are celestial or terrestrial

• all bodies, whether the bodies are big or small, whether

  they are celestial or terrestrial.

• None of the above
