Homework Statement
If period of simple harmonic graph of electric current goes down by 20%, how will change the angular frequency?
Will it increase by 25π%? 25%? 50%?...
Homework Equations
T = 2π/ω
The Attempt at a Solution
So by going down by 20%, so 100%-20%, I have 80%*T=2π/ω. 0.8*T=2π/ω. 8T/10=2π/ω. 4T/5=2π/ω. ω=2π/T *(5/4) = 2π/T * 1.25
So by this, angular frequency increases by 25%?
