Question

2. A block of mass 8 kg is kept on a rough horizontal surface; when a
force of 15 N is applied upon the
block, then it does not move,
calculate the force of friction.​

Answer 1

Answer:

0.1875 is the friction

As force=friction × normal reaction

• F=f × mg
• 15=f × (8×10)

Answer 2

Answer:

f= p

p= 1
