Answer:
There are finally 4 rotations per second.
Explanation:
If a trapeze artist rotates once each second while sailing through the air, and contracts to reduce her rotational inertia to one fourth of what it was. We need to find the final angular velocity. It is a case of conservation of angular momentum such that :
Let 
, 
and 
So,
So, there are finally 4 rotations per second. Hence, this is the required solution.

Answer:
F = 180 N
Explanation:
Given that,
Charge, q₁ = 10 μC
Charge, q₂ = 20 μC
The distance between the charges, r = 10 cm = 0.1 m
We need to find the magnitude of the electrostatic force. The formula for the electrostatic force is given by :
So, the magnitude of the electrostatic force is 180 N.
