Question

Every Body in the universe attract each other with a force called force of gravitation this force is directly

proportional to the product of masses of two bodies and inversely proportional to the sq of distance btw

there centers F=(Gm1m2)/r2

, G=universal gravitational constant

A . The Universal constant of gravitation G has the unit

a)N b)m/s c) (Nm2

)/kg2

d) J

B . The force acting on a ball due to the earth has a magnitude Fb and that acting on the earth due to

the ball to the ball has a magnitude Fe. Then

a) Fb=Fe b) Fb>Fe c)Fb<Fe d)Fe=0

C . The force of gravitation between two bodies of mass 1kg each kept at a distance of 1m is

a)6.67 N b)6.67 x10-9 N c)6.67 x10-10 N d)6.67 x10-11 N
