Answer:
b) Nothing will happen,  the sea saw will still be balanced. 
Explanation:
b) Nothing will happen,  the sea saw will still be balanced. 
Reason:- 
When two kids are balanced, the sum of torques on the seesaw will be zero. 
if each kid, reduces their distances by half, then the torque of each kid will be half and the sum of torque of each on the seesaw will be zero. 
Therefore the seesaw is balanced

The speed at which the objects were attracted to each other determined by the gravitational pull. 
<h3>What is gravity?</h3>
The force of attraction felt by a person at the center of a planet or Earth is called as the gravity or gravitational pull.
The gravitational force, Fg is the attractive force exerted by the Earth on the object that is equal to the mass of the object times the gravitational acceleration. 
When the two objects are attracted, the speed with which they are moving toward each other depends on the strength of the pull force. This pull force is the gravitational pull.
Thus, the speed at which the objects were attracted to each other determined by the gravitational pull.
