Question

A force F = i +4j acts on the block shown. The force of friction acting on the block is​

Answer 1

Answer:

to come to an arrangement as to a course of action. ...Gandhiji decided to withdraw the Non-Cooperation Movement due to various incidents of violence perpetrated by the masses, especially the Chauri Chaura incident in 1922 where the people clashed with the police, setting a police-station on fire.

Answer 2

Given:-

F = i + 4j

To Find:-

Force of Friction acting on the block is = ?

Solution:-

The maximum value of friction is $\sf{f_max}$=µN

Here N + 4 = mg = 10

$\sf{\implies}$N = 6N

$\sf\implies{f_max}$=0.4 × 6 = 2.4N

But applied force in horizontal direction is $\sf{f_h}$=1N

$\sf{f_h<f_max}$.

So, static friction comes into play.

Fh= f

f =1N

f = -i
