When acceleration of $5\ kg$ block is $2\ m/s^2$ as shown in figure, then what will be the acceleration of $15\ kg$ block ............ $m/s^2$

A

$2$

B

$5$

C

$6$

D

$\frac{{20}}{3}$

Solution

$5 \times 2=\mathrm{kx}$

$100-\mathrm{kx}=15 \times \mathrm{a}$

$100-10=15 \times a$

$a=6 \mathrm{m} / \mathrm{s}^{2}$
