Question

One end of a rod is pivoted and the rod is rotating in a horizontal plane at a constant angular speed
w. A tiny bug on the rod moves away from the fixed end at a constant speed u with respect to the
rod. Which of the following is true about its centripetal acceleration ?​

Answer 1

PLEASE MARK MY ANSWER AS BRAINLIEST!!!

-> L = [mr2]ω

L = [mv2t2]ω 

L = mv2ωt2

τ=δtδL = 2mv2ωt (directly differentiate the eq. given above)

τ∝t

Therefore, straight line passes through ( 0,0 )

-> Centripetal acceleration, property of the motion of a body traversing a circular path. The acceleration is directed radially toward the centre of the circle and has a magnitude equal to the square of the body's speed along the curve divided by the distance from the centre of the circle to the moving body.
