Question

A pendulum of 14cm long oscillates
through an angle of 12°, then the angle
of the path described by its extrimities is?
Answer in terms of degrees​

Answer 1

Answer:

Step-by-step explanation:

=> Here, A pendulum of 14cm long oscillates  through an angle of 12°

thus, Length of pendulum, r = 14 cm

And, θ = 12 degree = 12 x π/180 = π/15

=> Thus, the length of path described by its extrimities is,

Length of path = r x θ

                       = 14 x π/15

                       = 14π/ 15 cm

                       = 43.96 / 15 cm

                       = 2.93 cm

Hence, the length of the path is 2.93 cm.
