A block of mass 8 ~kg is suspended by a rope of length 3 ~m from the ceiling. A force of 40 ~N is applied horizontally to the block. Then the angle that the rope makes with the vertical in equilibrium is (acceleration due to gravity =10 ~m ~s ⁻² , neglect the mass of the rope)
Options
- A⁻¹ ( 1 2 )
- B⁻¹ ( 1 2 )
- C⁻¹ ( 1 3 )
- D⁻¹ ( 1 3 )
Correct answer
B. ⁻¹ ( 1 2 )
Step-by-step solution
Let ' ' be the angle that string makes in equilibrium. So, F = T ...(i) mg = T ...(ii) Dividing (ii) by (i), we get aligned & F mg = = 40 80 = 1 2 & = ⁻¹ ( 1 2 ) aligned
