1.
The value of force of gravity on
a body of mass 60kg was found to be 588N. Find the value of G taking mass of
the earth 6X1024 kg and
radius of the earth is 6.4X106 m.
2. calculate the gravitation force between Jupiter
and sun. given that: mass of Jupiter
=1.89X1027 kg mass of sun =2X1030 kg radius of
Jupiter orbit = 7.7X1011 m and G= 6.67X10 Nm2 /kg2 .
3. if you
weigh 40 kg on the earth , how far away from the surface of the earth
you weigh 20 kg?
4. when a ball is thrown vertically upwards
; it travels a distance of 19.6m. Find (i) the initial velocity of the ball.
(ii) the time taken by the ball to come back on the ground. (g=9.8 m/s)
5. A stone
is dropped from
