A constant force is applied on a `10kg` mass at rest. The ratio of work done in `1^(st)`,`2^(nd)` and `3^(rd)` second will be

Two masses 5kg and 2kg connected by a string are at rest on a smooth horizontal surface. A con stant force IN is applied on 5kg mass as shown in the figure. Two seconds later the string connecting the masses is cut but 'F' continues to act. After two more seconds

A ball is released from the top of a tower. The ratio of work done by force of gravity in 1st second, 2nd second and 3rd second of the motion of ball is

A ball is released from the top of a tower. The ratio of work done by force of gravity in 1st second, 2nd second and 3rd second of the motion of ball is

A body is freely dropped from a height h above the ground. Find the ratio of distances fallen in first one second, first two seconds, first three second first two seconds, first three seconds, also find the rato of distances fallen in 1^(st) second, in 2^(nd) second, in 3^(rd)

A vertical spring of force cosntant 100 N//m is attached with a hanging mass of 10 kg. Now an external force is applied on the mass so that the spring is stretched by additional 2m. The work done by the force F is (g = 10 m//s^(2))

Calculate the ratio of energies of He^(+) for 1^(st) & 2^(nd) excited state.

The 1^(st) , 2^(nd) and 3^(rd) terms of an arithmetic series are a , b and a^(2) where 'a' is negative. The 1^(st) , 2^(nd) and 3^(rd) terms of a geometric series are a , a^(2) and b respectively. The sum of infinite geometric series is

The 1^(st) , 2^(nd) and 3^(rd) terms of an arithmetic series are a , b and a^(2) where 'a' is negative. The 1^(st) , 2^(nd) and 3^(rd) terms of a geometric series are a , a^(2) and b respectively. The sum of the 40 terms of the arithmetic series is
