The block m does not slip over M'
From ure i. `T-N sin theta = M'a` ………….i.
`From ure ii, N cos theta = Mg`…..ii.
` N sin theta = Mg ……….iii`
` From ure iii, Mg-T=Ma`.......iv.
From equations i. and iv
`Mg-N sin theta = (M'+M) a`

From equation (ii),
`Mg-Mg tan theta j= (M'+M)a`
and a= g tan theta
`Mg-Mg tan theta = (M'+M)g tan theta`
:. M= (M'+M)/(cot theta -1)`.

A square coil of side 10 cm consists of 20 turns and carries a current of 12 A. The coil is suspended vertically and the normal to the plane of the coil makes an angle of 30^@ with the direction of a uniform horizontal magnetic field of magnitude 0.80 T. What is the magnitude of torque experienced by the coil?

Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.

Assertion: A vector quantity is a quantity that has both magnitude and a direction and obeys the triangle law of addition or equivalent the parallelogram law of addition. Reason: The magnitude of the resultant vector of two given vectors can never be less than the magnitude of any of the given vector.
