Answer:
648.40N
Explanation:
Centripetal acceleration is the acceleration of an object around a circular path. Centripetal for e acting on the combined mass is expressed as:
F = ma
F = mv²/r
m is the mass of the object = 143kg
v is the linear velocity = 13.8m/s
r is the radius = 42.0m
Substitute the given parameters into the formula;
F = 143*13.8²/42
F = 27,232.92/42
F = 648.40N
Hence the magnitude of the centripetal force acting on the combined mass is 648.40N
As the skydiver accelerates she gains momentum, and the air she passes through creates a resistance that pushes back up at her, increasing drag. Eventually, the force of the resisting air balances out with the force of gravity, and the skydiver stops speeding up

The gravitational attractions are greatest be when the objects have large masses and they're closer together. Their sizes don't matter.
The distance between the similar charges is 0.753 m. The electric force is the inverse of the square of the distance.
<h3>What is electric force?</h3>
Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.
The given data in the problem is;
q₁,q₂ are the charges = 1.6 ×10⁻¹⁹ C
R is the distance
F is the electric force=2.0×10²⁴ N
The electric force is found as;
Hence, the distance between the similar charges is 0.753 m.
