10.
A block ot mass 20 kg lying on a rough horizontal plane is connected by a light string passing over a smooth pulley to another mass 5 kg, which can move freely in the Vertical direction, as shown in the below figure. The tension in the string will __________ with the increase in coefficient of friction.

A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are unavailable.

Coefficient of friction = m1g/(m1+m2).
= (5/25)g.
Tension = m1m2g/(m1+m2).
= 15g/4.
So both +ve so increase.
= (5/25)g.
Tension = m1m2g/(m1+m2).
= 15g/4.
So both +ve so increase.

The tension won't change whether you increase or decrease the friction coefficient. It is always 50N.

T = (W1.W2(1 + u))/(W1 + W2).
u ->coef of friction.
W1,W2 -> weights.
u ->coef of friction.
W1,W2 -> weights.

According to me it will not affect.
