The co-ordinates of a moving particles at a time `t`, are give by, `x = 5sin 10t, y = 5 cos 10t`. The speed of the particle is:

A

`25`

B

`50`

C

`10`

D

None

Text Solution

Verified by Experts

The correct Answer is:
B
`x = sin 10t, y = 5cos 10t`
`x^(2) +y6(2) = 5^(2)`
Particles is moving on circle of radius `5`
