100- h) = 0 – 1/2 gt2 g be negative be cause or h = 100 – 1/2 gt2 …. (1) its direction be downward
For B –
h = 50t – 1/2 gt2 …… (2)
From 1 and 2
or 100 = 50t
or t= 2 sec

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
