Question

Ayesha and Anita are pulling a table using ropes tied at the two ends of the table. Ayesha is applying force of 35N and Anita is applying a force of 45N. Find out the net force acting on the table and direction of motion of the chair.

Answer 1

Answer:

Let the accelerations in both cases are a and a

′

respectively.

The tension is given as,

T−mg=ma (1)

2mg−T=2ma

By adding equations (1) and (2), we get

mg=3ma

a=

3

g

In the second case the tension is given as,

T

′

−mg=ma

′

(3)

2mg−T

′

=0 (4)

By adding equations (3) and (4), we get

mg=ma

′

a

′

=g

The ratio of acceleration is given as,

a

=
