Question

force of friction on a body kept on the surface​

Answer 1

Explanation:

For a body on a rough surface, maintaining motion is easier as compared to initiating it. g. Attributed to resultant of normal reaction and coefficient of friction between the surfaces

Answer 2

Answer:

is perpendicular to the surface of body.

Explanation:

if we move the body the perpendicularity of force will tend to oppose linearly.as given in the figure..

1. the arrow is showing direction of friction.
2. you should read whatever I written first and then visit pic given
3. observe (1) then (2) and then (3)

if understood then please follow me bro..
