The displacement of a particle in SHM is...

The displacement of a particle in `SHM` is `x = 3sin (20 pit) +4 cos(20pit)cm`. Its amplitude of oscillation is

A

3 cm

B

4 cm

C

5 cm

D

25 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`a_(1) = 3, a_(2) = 4, phi = 90^(@)`
Resultant complitude `= sqrt(a_(1)^(2) + a_(2)^(2)) = 5`
