A and B are two points on uniform metal ring whose centre is O The angle AOB =theta . A and B are maintaind at two different constant temperatures When theta =180^(@) the rate of total heat flow from A to B is 1.2W When theta =90^(@) this rate will be .

A and B are two points on a uniform metal ring whose centre is C. The angle ACB=theta . A and B are maintained at two different constant temperatures. When theta=180^(0) , the rate of total heat flow from A to B is 1.2 W. When theta=90^(0) , this rate will be

In a uniform ring of resistance R there are two points A and B such that /_ ACB = theta , where C is the centre of the ring. The equivalent resistance between A and B is
