The torque Is maximum when the normal to the loop is _ ____to `barB`.

Of all the cylinders with given surface area, show that the volume is maximum when height is equal to the diameter of the base .

The rotational analogue of force is moment of force, also called torque. The turning effect of force is maximum when the angle between r and F is.

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the loop. What is the emf developed across the cut if the velocity of the loop Is 1 cm//s In a direction normal to the shorter side of the loop? For how long does the induced voltage last in each case?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the loop. What is the emf developed across the cut if the velocity of the loop Is 1 cm//s In a direction normal to the longer side. For how long does the induced voltage last in each case?
