Two equal masses are held at a distance of `3.0cm` in a line and released simulataneously. What will be the separation between them after `2s`?

Two lead spheres are kept at a distance of 30 cm . The mass of each sphere is 100 kg. The mutual force of gravitational attraction between them is equal to the weight of a mass of 0.75 mg. Determine the gravitational constant .

Two particles have equal masses of 5.0 g each and opposite charges of +4.0 xx10^(-5) C. They are released from rest with a separation of 1.0 m between them. Find the speeds of the particles when the separation is reducced to 50 cm.

Two balls are released from the same height at an interval of 2s. When will the separation between the balls be 20m after the first ball is released? Take g=10m//s^(2) .

Two bodies are held separated by 9.8 m vertically one above the other. They are released simultaneously to fall freely under gravity. After 2 s the relative distance between them is
