The weight of a body on the moon is ___ of that on earth.
1/8
1/4
1/9
1/6
The weight of a body on the moon is one - sixth of its weight on the earth.How will be the mass of the body vary ?
becomes 1/6 th
remains the same
becomes 6 times
becomes 1/8 th
The earth attracts a body of mass 2kg kept on its surface with a force of
9.8 N
6.67 x 10-11 N
1 /9.8 N
19.6 N
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
S.I unit of gravitational constant 'G' is
Nm2 kg2
Nm2/kg2
N/m2 kg2
N/m2 kg-2
Calculate the gravitational force of attraction between a woman weighing 50 kg and her child of 12 kg separated by a distance of 2m.
10-8 N
10-13 N
10-11 N
10-12 N
The numerical value of G is :
6.67 x 10-11 Nm2/kg2
6 x 1024 kg
6.4 x 106 m
6.67 x 10-11 Nm2/kg
The equation for the Universal Law of Gravitation is :
F = Gm1m2/r2
F = Gr2/ m1m2
F = G(m1/m2)r2
F = (m1m2/r2)
On the earth acceleration due to gravity, 'g' is minimum at
equator
magnetic north pole
magnetic south pole
poles
For a freely falling body (falling vertically downwards) acceleration due to gravity, 'g' is
negative
positive
zero
none of these
