A block of mass m = 4kg is placed over a rough inclined plane having coefficient of friction $\mathrm{\mu }$ = 0.6 as shown in fig. A force F = 10N is applied on the block at an angle ${30}^o$ . The contact force between the block and the plane is

• A

  10.65N

• B

  16.32N

• C

  27.15 N

• D

  32.16 N
