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 )
Text Solution
Verified by ExpertsThe correct answer is:
C
Reading of spring balance is same as tension in the balance.
T = 10 g = 98 N
T = 2 a [Newton’s II law for 2 kg block]
a = 49 m/s 2
