$$f = 20 - 10 = 10$$ N
Here, we will provide a sample solution to a few numerical problems from the M Karim Physics Numerical Book for Class 11. m karim physics numerical book solution class 11
A block of mass 5 kg is placed on a horizontal surface. A force of 20 N is applied to the block, causing it to move with a uniform acceleration of 2 m/s². What is the coefficient of friction between the block and the surface? $$f = 20 - 10 = 10$$ N
