Question

. Two discs are in contact with each other. The axis of both the discs has been fixed. They can only rotate. A force F has been applied tangentially on larger disc. Assuming sufficient friction between contact surfaces. The angular acceleration of smaller disc is (1) 2F R₂(m, + m2) m F m2 2F (2) R R2 R,(m+ m) F (3) R2(m, + m) F (4) R R, (m. + m2)\

Answer 1

Answer:

2N

Explanation:

Tractive force, is the force used to generate motion between a body and a tangential surface, through the use of dry friction, though the use of shear force of the surface is also commonly used.

Let the force be

f

′

.

Since both the discs were rotating without slipping,

α

=1

By applying torque equation at the centre of second disc,f(2R)=[ 22×(2R)2 ]α 2

⇒f=2R=2N
