The acceleration of a body moving up a rough inclined plane when it is pulled up by a force, depends only on its mass.

Question

Verified by Toppr

Answer 1

The force required to move a body up an inclined plane having coefficient of friction $μ$ is given by:
$F = m g (s i n α + μ c o s α)$ . So the acceleration of the body will be:
$a = F / m = g (s i n α + μ c o s α)$ which is independent of its mass.

in this case friction acts opposite to the applied force.

Answer 2

The force required to move a body up an inclined plane having coefficient of friction

μ

is given by:

F = m g (s i n α + μ c o s α)

. So the acceleration of the body will be:

a = F / m = g (s i n α + μ c o s α)

which is independent of its mass.

in this case friction acts opposite to the applied force.

The acceleration of a body moving up a rough inclined plane when it is pulled up by a force, depends only on its mass.

Frictional force acts in the direction of the applied force.

The force required to move a body up an inclined plane having coefficient of friction μ is given by:F=mg(sinα+μcosα). So the acceleration of the body will be:a=F/m=g(sinα+μcosα) which is independent of its mass. in this case friction acts opposite to the applied force.
