Question

6. Two bodies of different masses ma and mb are dropped from two different heights a and b. The ratio of the
time taken by the two to cover these distances are
B) b:a
C) √a:√b
D) a2:b2​

Answer 1

Answer:

C

Explanation:

acceleration due to gravity is independent of mass of the body.

for body Ma, a=1/2gTa^2

Ta=√2a/g

similarly for body Mb, Tb=√2b/g

so,Ta:Tb=√a:√b
