MCQs are made in such a way that no important aspect is missed out. Any student taking a test and getting more than 90% marks here, will surely get same marks in board exam.
The work is product of force and velocity? Work done in gravitational force along a closed path is always zero? Work done in a gravitational field is dependent of the path followed by the body? Gravitational field is a non-conservative field? The work done by a force of 10N applied parallel to direction of motion up to 20 m is?
The work done is said to be negative when force and displacement are? The work done in a gravitational field is always independent of the …………? Joule = ………? is the power needed to perform 1 Joule of work in 1 Sec? SecThe value of gravitational P? E for a particular body above the ground is equal to ………? The velocity needed to get rid off earths gravitational field is called ……………? Write the expression of work done by a fore that act at an angle 600 to a moving body? A body of 1 kg is lifted to a height of 10m above the ground what is the work done on the body?A mason of 100N weight is climbing on a 10m high ladder? Find his PE at the middle of ladder? A ball of weight 98N is moving on a frictionless surface with a velocity of 1m/s? Compute its K? E? A force of 50N acts though a distance of 100m? Compute the work done with the help of graph?
