Question:

What should be the conditions under which someone wins a match of Tug-Of-War regarding the weight and force applied on the rope?

Prakhar M.
Answer:

The One who applies more friction force (shear force) on the ground will win because friction will resist the slipping between the surface and the person.

Question:

What is the difference between the center of Buoyancy and center of Mass?

Prakhar M.
Answer:

The center of buoyancy for an object is the center of mass for the fluid it displaces. Whereas center of gravity is a point from which the weight of a system can be considered to act.

Question:

Two identical conducting rings A&C of radius r are in pure rolling over a horizontal conducting plane with the same speed(of their center of mass) "v" but in opposite direction. A constant magnetic field B is present pointing inside the plane of the paper. Then calculate the potential difference between highest points of the two rings in terms of B, v, and r

Prakhar M.
Answer:

4Bvr is the answer. Consider rotation of the rings about their lowest points diametrically. e = [Bw(omega)(2r)^2] / 2 = 2Bvr at A with respect to plane (since pure rotation). and e = -2Bvr at B with respect to the plane. So, the potential difference between these two points = 4Bvr.
