Every object in the universe attracts every other object with a force which is inversely proportional to
square of the distance
distance
cube of the distance
product of masses

When you put an object on a spring balance,do you get mass of an object or its weight ?
weight
force
mass
acceleration
Kepler’s concept propounded that the
Sun was stationary at the centre of the universe with the planets revolving around it in orbits.
The earth is stationary and is at the centre of the Universe, with the sun , moon, planets and stars, revolving around the earth.
Planets revolving around the sun in elliptical orbits with the sun at one of the foci of the ellipse.
The mass of a body is measured to be 12kg on earth. If it is taken to moon, the mass will be
72 kg
2 kg
12 kg
24 kg

16 times
12 times
4 times
10 times
For a freely falling body (falling vertically downwards) acceleration due to gravity, 'g' is
negative
positive
zero
none of these
The geocentric theory propounded that the
The earth is stationary and is at the centre of the universe, with the Sun , moon, planets and stars, revolving around the earth.
Planets revolving around the Sun in elliptical orbits with the Sun at one of the foci of the ellipse.
The earth attracts a body of mass 2kg kept on its surface with a force of
9.8 N
