Question

Example 1
A body of mass 'm' is kept on the
horizontal floor and it is pushed in the
horizontal direction with a force of 10N
continuously, so that it moves steadily.
a) Draw FBD(a diagram showing all the
forces acting on the body at a point of
time)
b) What is the value of friction?​

Answer 1

Answer:

by equating horizontal forces which are acting on the body we will get

frictional force = 10

Answer 2

Value of friction = M.N

Here,

M= friction constant

N= normal force.

From the given question N = mass *gravity

So, friction = M.mg
