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)
    increase
  • b)
    decrease
  • c)
    not be effected
Correct answer is option 'A'. Can you explain this answer?

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

1) friction means the resistance to motion of one object moving relative to another.2) a coefficient of a friction is a value that shows the relationship between force of friction between two objects and the normal force between the objects.3)here In this case the coefficient of friction shows value between string and mass of block.4)hence the tension on the string will increase with the increase in the coefficient of friction.
