An object is placed at some distance from a radio station. If the interval between transmission and reception of pulses is `2.66xx10^(-2)`S, then find the distance.

A

4000 km

B

2000 km

C

3000 km

D

2500 km

Text Solution

Verified by Experts

(a) `2x=ct`
`x=(ct)/(2)=(3xx10^(8)xx2.66xx10^(-12))/(2)implies x ~=4000 Km`
