Question

Tension in the string is :
a) 5N b)25N c) 10N d)0​

Answer 1

T=mgsin@ in linear direction

mgsin@=5*10*1/2

T=25N

Answer 2

Answer:

Tension in the string is 25 N.

Step-by-step explanation:

Given: Mass, m = 5 kg

          Angle, ∅= 30°

To find: Tension T in the string.

Solution: We know that for an inclined plane, when the component of forces acting on the mass on the inclined surface, the force with which the mass slides down is mg sin ∅.

So,               Tension, T = mg sin ∅

                           T = 5 × 10 × sin 30°

                           T = 50 × 1/2

                           T = 25 N.

Hence, the tension in the string is 25N.
