How does mass affect the force of gravity between 2 objects?

Force due to gravity increases on increasing the masses and decreases on decreasing the masses.  

Explanation:

The force due to gravity (F) acting between any two given bodies can be expressed as,

Here,

G = gravitational constant

= mass of the first body

= mass of the second body

separation between the bodies

It is clear from the above expression that the force due to gravity acting between the two bodies is directly proportional to the product of the masses of the bodies.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

total distance/total time

(85 + 82)/(5+3)

167/8
