A heavy body of mass `25kg` is to be dragged along a horizontal plane (mu = `(1)/(sqrt(3))`. The least force required is `(1 kgf = 9.8 N)`

A block of mass 50kg rests on a rough horizontal plane whose coefficient of static friction is 0.3 . What is the least force required to just move it if it is pulled (i) horizontally and (ii) at 45^(@) to the horizontal.

A body of mass 1kg is moving along a straight line with a velocity of 1m//s . The external force acting in the body is

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 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 block of mass 5kg is placed on a rough horizontal plane whose coefficient of friction is 0.3 . Find the least horizontal force needed to move the block along the plane and the resultant of normal reaction and the force applied.

A block of mass m=1/3 kg is kept on a rough horizontal plane. Friction coefficient is mu=0.75 . The work done by minimum force required to drag to the block along the plane by a distance 5m is :-
