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.
