Question

The ratio of tension t1 and t2 is ( strings are massless )

Answer 1

Explanation:

Correct option is

A

4

As masses of the both side of the pulley are equal so they will not move. Thus, the tension in the strings will be the weight of the blocks.

Thus, T

4

=4g and T

1

=1g

so, T

4

/T

1

=4

Answer 2

From the given question the correct answer is : tension T1 and T2 is 7 : 5 -

> The tension on T2 is 5kg as 5kg mass is pulling string of T1 -

> The tension on T1 is 7 kg as both the masses are right over t1 so ( 5kg + 2kg = 7kg ) ( no addison of string as it is massless )
