point charges q1 and q2 are placed in air at a distance r..the ratio of the force on charge q1 by charge q2 and force on q2 by charge q1 is
Hi Sivaa,
Force on a charge due to other charge is proportional to the product of the two charges and inversely proportional to the square of the distance between them.
Hence, if we are to take the ratio of the force on one charge due to other and vice versa then the ratio will be 1.
