The work done by any non-conservative force is not reversible-explain.

Statement I : For a charged particle moving form point P to point Q, the net work done by an electrostatic field on the particle is independent of the path connecting points P and Q. Statement II : The net work done by a conservative force on an object moving along a closed loop is zero.

Is air resistance a conservative force ?

Statement I: if work done by conservative force is negative then potential energy associated with that force should increase. Statement II: This is from the reaction Delta u =- W. Here Delta u is change in potential energy and W is work done by conservative force.

Work done in the reversible expansion is

Work done by magnetic force is zero. Explain.

Centripetal force does no work' - explain.

What are conservative forces ? Give an example.

Define conservative force. Show that the work done around a closed path in a conservative force field is zero.

Work done by 3 mol of an ideal in an isothermal reversible expansion of 30^(@)C is 9.5 kJ. If the initial volume of the gas is 20 L, then what will be the final volume of the gas?

Define conservative force . Show that the work done around a closed path in a conservative force field is zero .
