Question

A block of mass m is resting on horizontal surface, contact force between block & surface is N, then​

Answer 1

Answer:

ANSWER

Normal force, N=mg−Tsinθ

Tcosθ−μN=ma

From above equations:

a=

M

T

(cosθ+μsinθ)−μg

Answer 2

• A block of mass m is resting on horizontal surface, contact force between block & surface is N, then. N is equal to mg & both forces are electromagnetic.

• Both forces are different in nature but due to equilibrium, forces are equal & opposite.
