Two point charges, each of `4 mu C` when placed in vacuum, repel each other with a force of 1.6 Newton. Calculate the distance between the two charges.

Two point charges of 2 coulomb and 6 coulomb repel each other with a force of 12 newton. If each charge is given an additional charge of -2 coulomb then the force between them will become

Two point charges +3 muC and +8 muC repel each other with a force of 40 N. if a charge of -5 is added to each of them, then the force between them will become

Two point masses each equal to 1 kg attract one another with a force of 9.8 ×10^(-9) kg-wt. the distance between the two point masses is approximately (G = 6.6 xx 10^(-11) "MKS units")

Two point charges of 5muC and 15 muC are placed in air 20cm apart. Find the electric potential at the middle point of the line joining the two charges.

Two equally charged, identical metal spheres A and B rpepel each other with a force F. the spheres are kept fixed with a distance r between them. A third identical, but uncharged sphere C is brought in contact with A and then placed at the mid-point of thr line joining A and B. the magnitude of the net electric force on C is

Two point charges whose magnitudes are in the ratio 3 : 2 repel each other with a force 135 xx 10^14 N when they are 4 cm apart in air. Find the magnitude of each charge.

Two charges q_1 and q_2 repel each other with a force of 0.1 N . What will be the force exerted by q_1 on q_2 , when a third charge is placed near them?

Two point charges 4muC and -2muC are separated by a distance of lm in air. Calculate, on which point on the line joining the two charges, is the electric potential zero?

Two point charges repel each other with a force of 100 N. one of the charges is increased by 10% andother is reduced by 10% . The new force of repulsion at the same distance would be

Two point charges + 0.2muC and 0.01muC are placed 10cm apart. Calculate the work done in reducing the distance 5cm between them.
