MCQ

Figure shows two blocks connected by a light inextensible string as shown in figure. A force of $10 \,N$ is applied on the bigger block at $60^{\circ}$ with horizontal, then the tension in the string connecting the two masses is ....... $N$

A
$5$
✓
$2$
C
$1$
D
$3$

✓

Answer

Correct option: B.

$2$

b
(b)

$F_{\text {net }}=M a$

$\left(10 \cos 60^{\circ}\right)=(3+2) a$

$a=1 \,m / s ^2$

$T=2(1)=2 \,N$
