Question
A massless spring balance is attached to 2 kg trolley and is used to pull the trolley along a flat surface as shown in the fig. The reading on the spring balance remains at 10 kg during the motion. The acceleration of the trolley is (Use g = 9.8 ms-2)
Options
A.4.9 ms-2
B.9.8 ms-2
C.49 ms-2
D.98 ms-2
Solution
Reading of spring balance is same as tension in the balance.
⇒ T = 10 g = 98 N
T = 2a [Newton′s II law for 2 kg block]
⇒ a = 49 m/s2
