144026 A particle tied to a string of negligible weight and length \(l\) is swinging in a horizontal circular path with constant angular velocity having time period \(T\). If the string length is shortened by \(\frac{l}{2}\), while the particle is in motion, the period is:

144027 A child starts running from rest along a circular track of radius ' \(r\) ' with constant tangential acceleration ' \(a\) '. After time ' \(t\) ' he feels that slipping of shoes on the ground has started. The coefficient of friction between shoes and the ground is \([\mathrm{g}=\) acceleration due to gravity]

144028 A body is moving along a circular track of radius \(100 \mathrm{~m}\) with velocity \(20 \mathrm{~m} / \mathrm{s}\). Its tangential acceleration is \(3 \mathrm{~m} / \mathrm{s}^{2}\), then its resultant acceleration will be

144030 A bucket containing water is revolved in a vertical circle of radius ' \(r\) '. To prevent the water from falling down, the minimum frequency of revolution required is \([\mathrm{g}=\) acceleration due to gravity]
