To solve this problem it is necessary to apply the equation related to the Gravitational Force, the equation describes that

Where,
G = Gravitational Universal Constant
M = Mass of Earth (or Bigger star)
m = Mass of Object (or smallest star)
r = Radius
From the statement we know that once the impact is made, the golf ball is subjected to the forces that are exerted in nature. Since the air resistance, which would represent the drag force, is ignored. Only the forces related to gravity remain.
The gravitational force carries 'pushes' or 'attracts' the body towards the earth, while the speed decreases as it reaches its maximum height.
When the ball has reached its maximum height only the force of gravity begins to act on it, generating the attraction to the earth in parabolic motion.
Therefore the correct answer is B.

Answer:
Force on the singly charged ion will be
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be 
It is given that ion so charge on ion will be equal to 
We have to find the electric force on the ion
Electric force is equal to
, here q is charge and E is electric field
So force on the charge will be equal to 
So force on the singly charged ion will be 
Momentum = mass x velocity
Momentum = 10.5 x 3
Momentum = 31.5 kgm/s
