If cosω−sinω=√2sinω then cosω+sinω=√2cosω
In a school the physics teacher decides to perform an experiment in the lab. He left an ideal spring block system to do SHM an a frictionless table.
Five students are sent in the lab one by one and asked to write the equation of the SHM.
Ram−Δ0 sin(ω t+π6)
Himanshu−Δ0 sin(ω t+2π3)
Satra−Δ0 cos(ω t+2π3)
Avinash−Δ0 sin(ω t+7π6)
Abhishek−Δ0 sin(ω t+5π6)
Anand was asked to point out whose equations were in same phase and whose were in opposite phase?
(i)Ram and Avinash(x) same phase
(ii)Abhishek &Avinash(y) Opposite phase
(iii)Ram &Satra
Satra&Avinash
