Three charges each 5.0x10-6C are situated at he corners of an equilateral triangle of side 1.0m. Find the force that charge q3 experienced due to the other two charges.
We know that
Force
F1=kq3q1a2F_1=\frac{kq_3q_1}{a^2}F1=a2kq3q1
F2=kq2q3a2F_2=\frac{kq_2q_3}{a^2}F2=a2kq2q3
Fnet=3FF_{net}=\sqrt{3}FFnet=3F
Fnet=3×0.225=0.3897NF_{net}=\sqrt{3}\times0.225=0.3897NFnet=3×0.225=0.3897N
