Question

Two spheres a and b are placed between two vertical walls

Answer 1

Explanation:

two spheres A and B are placed between two vertical walls friction is absent everywhere the ratio of NA to NB is

Answer 2

When two balls are kept on the ground and are covered by two walls on both sides that forces acting on the two balls would be as follows:-

• Let us consider the ball that is kept on the lower side is “A” then there will be four forces acting on this ball.
• Force would be due to gravitational pull on the ground MG. Then, the force would be our towards the right side of the ball due to the pressure that is exerted by the left wall.
• Then, it would be on the upward direction that is due to the force that is exerted by the ground on the ball.
• And then would be the force that is exerted by the other ball which would be in the opposite direction of the placement of the second ball.

• Latest consider the second ball that is on the upper side to be “B” then there are three forces acting on this ball first force would be the gravitational pull of the ground mg.
• It would be on the left side that is exerted by the right side wall on the ball third force would be the opposite direction of the lower ball it would be the force exerted by ball “A”.
