A body of 2 kg mass slides down with an acceleration of 4 ~ms ⁻² on an inclined plane having slope of 30^ . The external force required to take the same body up the plane with same acceleration will be (Acceleration due to gravity =10 ~ms ⁻² )

Options

  1. A8 N
  2. B16 N
  3. C22 N
  4. D20 N

Correct answer

D. 20 N

Step-by-step solution

aligned & m =2 ~kg , a =4 ~m / s ^2 & 10- f =2 4 & f =2 ~N aligned When the body goes up the inclined plane aligned & F -10-2=2 4 & ~F =20 ~N aligned
