An air capacitor is made from two flat parallel plates 1.50 mm apart. the magnitude of charge on each plate is 0.0180 μc when the potential difference is 200 v.

The capacitance is 90 pF.

Explanation:

Given that,

Distance between the plates= 1.50 mm

Charge on each plate = 0.0180μC

Potential difference = 200 V

Suppose we find the capacitance

We need to calculate the capacitance

Using formula of capacitance

Where, Q = charge

C = capacitance

V = potential

Put the value into the formula

Hence, The capacitance is 90 pF.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
