Q. The friction coefficient between the table and the block shown in figure is $0.2$ . Find the tension in the string which is connected with both $5 k g$ blocks.

$68 N$

$96 N$

$34 N$

$12 N$

$f_{l} = μ m g = 0.2 \times 10 \times 5 = 10 N$
$T_{1} - 50 = 5 a .... (i)$
$T_{2} - T_{1} - 10 = 5 a .... (ii)$
$150 - T_{2} = 15 a .... (iii)$
From eq. $(i) (ii), (iii)$
$T_{1} = 68 N$

Q. The friction coefficient between the table and the block shown in figure is 0.2 . Find the tension in the string which is connected with both 5kg blocks.
