The disperod of a particle varies according to the relation `x=4 (cos pit+ sinpit)`. The amplitude of the particle is.

A

`8` units

B

`2` units

C

`4`sunits

D

`4sqrt(2)` units

Text Solution

Verified by Experts

The correct Answer is:
D
Phase difference between `cos pit` and `sin pi t` is `90^(@)`.
`A_(R) = 4sqrt(2)units`
