Question

A body of mass $2$ kg is at rest on a horizontal table. The coefficient of friction between the body and the table is $0.3$ A force of $5N$ is applied on the body. The acceleration of the body is

• A. $0m{s}^{-2}$
• B. $2.5m{s}^{-2}$
• C. $5m{s}^{-2}$
• D. $7.5m{s}^{-2}$

Answer 1

The correct option is A $0m{s}^{-2}$

frictional force on the body = $\mu N$

$⟹0.3\ast 2\ast 9.8$ N

$⟹5.88$ N

Hence, as frictional force is more than the force applied so the body wont move and so no acceleration.
