Question 7 of 10

8. A block of mass m is pulled by applying a force F at an angle θ with the horizontal surface. Its acceleration will be given by

A

B

C

D

Question 8 of 10

9. Consider two blocks of masses m1 and m2 placed in contact with each other on a friction less horizontal surface. Let a force F be applied on block of mass m1, then the value of contact force between the blocks is

A

B

C

D

Question 9 of 10

10. A block of mass m is pushed by applying a force F at an angle θ with the horizontal surface. The normal force on the block is given as -

F = mg - F sin θ

F = mg + F sin θ

F = F sin θ

F = mg
