प्रश्न
Long answer type question.
Define coefficient of static friction and coefficient of kinetic friction. Give the necessary formula for each.
उत्तर
- The coefficient of static friction is defined as the ratio of limiting force of friction to the normal reaction.
Formula: `mu_"S" = "F"_"L"/"N"` - The coefficient of kinetic friction is defined as the ratio of force of kinetic friction to the normal reaction between the two surfaces in contact.
Formula: `mu_"k" = "F"_"k"/"N"`

Calculate the coefficient of static friction for an object of mass 50 kg placed on horizontal table pulled by attaching a spring balance. The force is increased gradually it is observed that the object just moves when spring balance shows 50 N.
Answer the following.
A block of mass 37 kg rests on a rough horizontal plane having coefficient of static friction 0.3. Find out the least force required to just move the block horizontally.
A body of mass 37 kg rests on a rough horizontal surface. The minimum horizontal force required to just start the motion is 68.5 N. In order to keep the body moving with constant velocity, a force of 43 N is needed. What is the value of coefficient of static friction?
