each other by 0.01 m then the force between them is
​

Answer 1

Correct Question :

The force between two charges 0.06cm apart is 5N. If the charges are moved towards

each other by 0.01 m then the force between them is

Answer : 11.25N

Explanation :

Forces between 2 charges 0.06m apart is 5N we know, F = Kq1q2 / r2

S = Kq1q2 / (0.06)

Kq1q2 = 0.018 ⟶ (1)

F1 = Kq1q2 / [0.06−2(0.01)] ² each charge is moved towards the other by 0.04m

F ¹ = 0.018 / (0.04)

F¹ = 11.25N

Force will become newtons 11.25N.

Extra information :

Force :

Forces can be described as a push or pull on an object. They can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate.

Common symbols - F→, F, F

SI unit- newton (N)

Other units - Dyne, pound-force, poundal, kip, kilopond

In SI base units - Kg·m/s2

Derivations from

other quantities- F = m²

Newton :

The newton (symbol: N) is the International System of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
