Question

Two masses 2 kg and 0.5 kg are tied to the ends of a light string over a smooth pulley fixed at the edge of the table. The larger mass is resting on smooth horizontal table and the smaller mass is hanging vertically. Find the tension in the string. ( g= 9.8 m/s^2)

Answer 1

hope it is helpful.. if u like my explanation mark as brainlist.

Answer 2

Answer:

3.92N

Explanation:

Let the Two masses M1= 2 kg and M2 =0.5 kg are tied to the ends of a light string over a smooth pulley fixed at the edge of the table.

Gravity g= 9.8 m/s^2)

T=

$\frac{m1 \times m2}{m1 + m2} \times g$

$= \frac{2\times 0.5}{2 + 0.5} \times 9.8$

$= \frac{9.8}{2.5}$

$= 3.92$

Therefore

Tension in the string T is 3.92N
