JEE MATHEMATICS MCQ: RATE MEASURE

1 Easy

1 of 1

Application +4 | -1

An object is moving in the clockwise direction around the unit circle

{x^2} + {y^2} = 1.

As it passes through the point

\left( {\frac{1}{2},\frac{{\sqrt 3 }}{2}} \right),

,its

y

-coordinate is decreasing at the rate of 3unit per second.The rate at which the

x

-coordinate changes at this point is (in unit per second)

View answer and explanation

Correct option: B

3\sqrt 3

Option B (

3\sqrt 3

) is correct because it represents the rate at which the x-coordinate changes at the given point.
