The below mathematical formula is used in this calculator to find the force on charge 2 due to charge 1
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 Q_{1} due to Q_{2} a_{r12} and r values are 5 coulomb, 7coulomb, 2 and .25 respectively?
Solution
The given data
Q_{1} = 5
Q_{2} = 7
a_{r12}
r = 0.25
Step by step calculation
Formula to find the force on charge 2 due to 1 (F_{2}) = (Q_{1} Q_{2}/(4 π &epsilon r^{2})) a_{r12} (farads/meter)
substitute the values in the formula
= [(5 x 7)/(4 x π x ε x 0.25^{2})] x a_{r12} (farads/meter)
ε value for free space 8.85 x 10^{12}
= [(5 x 7)/(4 x π x 8.85 x 10^{12} x 0.25^{2})] x a_{r12} (farads/meter)
= 35/3.47539x 10^{11}
F_{2} = 10.07 x 10^{11}
