Gravitational force acted on a body is equal to the weight of body.If a body has mass 'm' the gravitational force acted on the body is given by-
Since ball A has mass 20Kg and ball B has mass 10 Kg.So obviously gravitational force acting on body A is two times the gravitational force acts on body B.
Hence body A has greater gravitational force.

Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...

Two Thrown Balls 1 2 3 45678 A blue ball is thrown upward with an initial speed of 19.8 m/s, from a height of 0.6 meters above the ground. 2.4 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 8.9 m/s from a height of 22.3 meters above the ground. The force of gravity due to the earth results in the bals each having a constant downward acceleration of 9.81 m/s2....

Three small metal balls are thrown at different speeds off the top
of a building to hit the ground 25m below. Sphere A is thrown
directly downward at 10m/s, while Sphere B is dropped from rest.
Sphere C is thrown upwards at 5m/s. Ignore the effects of air
resistance.
Calculate the time for each sphere to hit the ground below.
