A body moving along a straight line is brought to rest in `2 sec` by a force `F_(1)` and in `3 sec`. By a force `F_(2)` the ratio `F_(1)//F_(2)` is

The force acting on a body moving in a straight line is given by F = (3 t^2 – 4t + 1) Newton where t is in sec. If mass of the body is 1kg and initially it was at rest at origin. Find displacement between time t = 0 and t = 2 sec

Two small conducting spheres of equal radius have charges + 10 muC and -20 muC respectively and placed at a distance R from each other. They experience force F_(1) . If they are brought in contact and separated to the same distance, they experience force F_(2) . The ratio of F_(1) to F_(2) is

A force F is applied on a block kept at the smooth surface in contact with the wall. If the block is at rest, the forces applied by block on surface (1) is F_(1) and on surface (2) is F_(2) . Find (F_(1))/(F_(2)) (Take g=10 m//s^(2))

Two springs having spring constants 25N/m and 16N/m are stretched by forces F_(1) and F_(2) have equal potential energy. The ratio of the forces F_(1) "and" F_(2) is
