Force on charge calculator - step by step calculation, formula & solved example problem to find the force on charge 2 due to charge 1 in electrical engineering based on the input values of Q1 due to Q2 ar12, r and ε. The ε value is 8.85 x 10-12 farads/meter for free space or air.

## Force on Charge & its formula

The below mathematical formula is used in this calculator to find the force on charge 2 due to charge 1

### Solved Example

The below step by step solved example problem may helpful for users to understand how the input values are being used in such calculations.
Example Problem
Find the force on charge F2 in the free space, where the Q1 due to Q2 ar12 and r values are 5 coulomb, 7coulomb, 2 and .25 respectively?
Solution
The given data
Q1 = 5
Q2 = 7
ar12 r = 0.25

Step by step calculation
Formula to find the force on charge 2 due to 1 (F2) = (Q1 Q2/(4 π &epsilon r2)) ar12 (farads/meter)
substitute the values in the formula
= [(5 x 7)/(4 x π x ε x 0.252)] x ar12 (farads/meter)
