Question

two bodies of mass ma and mb are dropped from two different hieghts a and b.the ratio times taken by the two bodies to drop through these distances is

Answer 1

Tell me if it was helpful or not.
thank u.

Answer 2

for a body of mass m dropped from a height h the time taken is independent of its mass it is given by \[t \alpha c \sqrt{h/g}\] since g is gravitational constant and c is a constnt of proportionnality hence\[t \alpha \sqrt{h}\]
hence your answer will be \[t _{1}/t _{2}=\sqrt{a/b}\]

Answer 3

the ratio is 1/r squared....r is the distance
