Answer:
Distance, r = 3721.04 meters
Explanation:
It is given that,
Charges on both humans, 
Electric force of attraction between them, F = 650 N
We need to find the separation between two humans. It can be solved using the following formula as :



r = 3721.04 meters
So, the distance between the humans is 3721.04 meters. Hence, this is the required solution.
Answer:
Explanation:
Given mg = 4N .
m = 4 / g
At the bottom of the swing let centripetal acceleration be a
T - mg = ma
9 - 4 = ma
5 = 4 a / g
a = 5g / 4
