Given, the mass m = 5 kg

The resultant force F of the two forces 6N and 8N is given by,

F = $\sqrt{8^{2} + 6^{2}}$ = 10 N

Acceleration is given by F = ma, a = F/m = 10/5 m/s² = 2 m/s²

$\tan ? θ$ = 6/8, $θ$ = 36.86 $°$

Find the acceleration of 2 kg block shown in the diagram. (neglect friction)

Alok Kumar Singh

For 2 kg block

T – 2g sin37 = 2a . (i)

For 4 kg block

4g – 2T = $\frac{4 a}{2}$

2g – T = a . (ii)

T = (2g – a)

2g – a – 2g × $\frac{3}{5}$ = 2a

3a = 2g × $\frac{2}{5}$

$a = \frac{4 g}{15}$
