A satellite of mass $$m$$ is orbiting the earth (or radius $$R$$) at a height $$h$$ from its surface. The total energy of the satellite in terms of $$g_0$$ the value of acceleration due to gravity at the earth's surface is

In the graph shown the displacement of the body is $$5$$ seconds will be 

Determine force on P in the following system of the charges q kept vertices of an equilateral triangle of side 'a'.

A car moving along a straight highway with speed $$144$$ km/h is brought to stop within a distance of $$400\ m $$ with uniform retardation. How long does it take for the car to stop ? 

Refer to the system shown above. the ratio of tension $$T_1$$ and $$T_2$$ is

The ratio of the weight of a man in a stationary lift and when it is moving downward with uniform acceleration 'a' is $$3:2$$. The value of 'a' is (g = acceleration due to gravity)

$$1$$ amu is

Two light strings of length $$4cm$$ and $$3cm$$ are tied to a bob of weight $$500gm$$. The free ends of the strings are tied to pegs in the same horizontal line and separated by $$5cm$$. The ratio of tension in the longer string to that in the shorter string is

A bob is suspended from a ideal string of length 'l'. Now it is pulled to a side through $$60^0$$ to vertical and whirled along a horizontal circle. Then its period of revolution is

The dimensions of Planck's constant is
