A body of mass 10 ~kg is kept on a rough horizontal surface of coefficient of friction 0.3 . If a horizontal force of 50 ~N is applied on the body, then the acceleration of the body is (Acceleration due to gravity =10 ~ms ⁻² )
Options
- A5 ~ms ⁻²
- B2 ~ms ⁻²
- C3 ~ms ⁻²
- D1 ~ms ⁻²
Correct answer
B. 2 ~ms ⁻²
Step-by-step solution
Mass, m=10 ~kg Coefficient of friction, M =0.3 force, F =50 ~N . Acceleration, a = ? Net Force is given by, F-f_s=m a Here, f _ s = mg [frictional force] aligned & 50- mg = ma & 50-0.3 10 10=10 a & 10 a =20 & a =2 ~m / s ^2 aligned
