A solid body rotates about a stationary axis, so that its angular velocity depends on the rotation angle ? as ?= ?￢ﾂﾒ – k ?, where ?￢ﾂﾒ and k are positive constants.At the moment t=0, ?=0, the time dependence of rotation angle is
Options
(a) k?￢ﾂﾒe-ᵏᵗ
(b) (?￢ﾂﾒ/k)e-ᵏᵗ
(c) (?￢ﾂﾒ/k)(1-e-ᵏᵗ)
(d) (?￢ﾂﾒ/k)(1-e-ᵏᵗ)
