Two smooth tu...

Question

Two smooth tunnels are dug from one side of the earth's surface to the other side, one along with a diameter and the other along with a chord. Now two particles are dropped from one end of each of the tunnels. Both the particles oscillate simple harmonically along the tunnels. Let $T_{1}$ and $T_{2}$ be the time periods and $v_{1}$ and $v_{2}$ be the maximum speed of the particles in the two tunnels. Then :

A

T_{1} = T_{2}
