Question

Find the angle in radian though which a pendulum swings if its length is 75 cm and the tip describes an arc of length

15 cm

Solution

We know that in a circle of radius r unit, if an arc of length l unit subtends an angle θ radian at the centre, then  theta = l/r

It is given that r = 75 cm

Here, = 15 cm

Is there an error in this question or solution?
