A magnet is parallel to a uniform magnetic field. If it is rotated by `60^(@)`, the work done is 0.8 J. How much work is done in moving it `30^(@)` further

A magnet is parallel to a uniform magnetic field. The work done in rotating the magnetic through 60^(@) is 8xx10^(-5) J . The work done in rotating through another 30^(@) is

A bar magnet is initially parallel to the magnetic field in which it is placed. Work done u rotate it by 60^(@) is 2.6 J. Work done in rotating it further by 30^(@) will be

An electric dipole is along a uniform electric field. If it is deflected by 60^(@) , work done by agent is 2 xx 10^(-19)J . Then the work done by an agent if it is deflected by 30^(@) further is

Dipole is placed parallel to the electric field. If W is the work done in rotating the dipole by 60^@ , then work done in rotating it by 180^@ is

A magnet of magnetic moment M is rotated through 360^(@) in a magnetic field H, the work done will be

A magnet of magnetic moment M is rotated through 360^(@) in a magnetic field H, the work done will be
