Question

Calculate the force required to move a block of mass 20kg resting on horizontal surface

Answer 1

Hey dear,

¶ Static friction-
- Static friction is a force that keeps an object at rest.
- It must be overcome to start moving the object.

◆ Answer-
F = 200μs


◆ Explaination-
# Given-
m = 20 kg
g = 10 m/s^2

# Solution-
Let μs coefficient of static friction fir the block and horizontal surface.

Minimum force required to move object from its static position is -
F = μs.mg
F = μs × 20 × 10
F = 200μs

Hope this helps...
