Two objects of different masses falling freely near the surface of moon would
undergo a change in their inertia
experience forces of same magnitude
have different accelerations
have same velocities at any instant
The value of acceleration due to gravity
is same on equator and poles
is least on poles
is least on equator
increases from pole to equator
The gravitational force between two objects is F. If masses of both objects are halved without changing distance between them, then the gravitational force would become
F/4
F/2
F
2F
A boy is whirling a stone tied with a string in an horizontal circular path. If the string breaks, the stone
will not move any more
will move along a straight line tangential to the circular path
will move along a straight line towards the centre of the circular path
will continue to move in the circular path
Law of gravitation gives the gravitational force between
two charged bodies only
any two bodies having some mass
the earth and Sun only
the earth and a point mass only
The value of quantity G in the law of gravitation
is independent of mass and radius of the earth
depends on both mass and radius of earth
depends on mass of earth only
depends on radius of earth only
Two particles are placed at some distance. If the mass of each of the two particles is doubled, keeping the distance between them unchanged, the value of gravitational force between them will be
1/4 times
4 times
2 times
unchanged
The atmosphere is held to the earth by
earth’s magnetic field
clouds
gravity
wind
The force of attraction between two unit point masses separated by a unit distance is called
universal gravitational constant
gravitational field
acceleration due to gravity
gravitational potential
The weight of an object at the centre of the earth of radius R is
R times the weight at the surface of the earth
R21 times the weight at surface of the earth
infinite
zero
An object weighs 10 N in air. When immersed fully in water, it weighs only 8 N. The weight of the liquid displaced by the object will be
8 N
2 N
10 N
18 N
