T1-T2-m g=m a 600-300=m(20) (300/20)=m m=15 kg

Q. Reading shown in two extended spring balances, $S_{1}$ and $S_{2}$ is $60 k g$ and $30 k g$ respectively and lift is accelerating upward with acceleration $10 m / s^{2}$ . The mass is stationary with respect to lift. Find the mass of the block in kg.

$T_{1} - T_{2} - m g = ma$
$600 - 300 = m (20)$
$\frac{300}{20} = m$
$m = 15 k g$

Q. Reading shown in two extended spring balances, S1​ and S2​ is 60kg and 30kg respectively and lift is accelerating upward with acceleration 10m/s2. The mass is stationary with respect to lift. Find the mass of the block in kg.

T1​−T2​−mg=ma 600−300=m(20) 20300​=m m=15kg
