The displacement y in centimetre is given in terms of time t second by the equation y=3 314 t+4 314 t The amplitude of SHM is :
Options
- A7 cm
- B3 cm
- C4 cm
- D5 cm
Correct answer
D. 5 cm
Step-by-step solution
aligned y & =3 314 t+4 314 t & =r 314 t+r 314 t aligned =r (314 t+ ) ...(i) r^2 ( ^2 + ^2 )=3^2+4^2=25 or r=5 ~cm
