270291 A car is moving in a circular horizontal track of radius\(10 \mathrm{~m}\) with a constant speed of \(10 \mathrm{~ms}^{-1} \cdot \mathbf{A}\) plumb bob is suspended from the roof of the car by a string of length \(1 \mathrm{~m}\). The angle made by the string with vertical is \(\left(g=10 \mathrm{~ms}^{-2}\right)\)

270292 A vehicle is moving with a velocity \(v\) on a curved road of width \(b\) and radius of curvature \(R\). For counteracting the centrifugal force on the vehicle the difference in elevation required in between the outer and inner edges of the road is

270293 The centripetal force required for a\(1000 \mathrm{~kg}\) car travelling at \(36 \mathrm{kmph}\) to take a turn by \(90^{\circ}\) in travelling along an arc of length \(\mathbf{6 2 8} \mathrm{m}\) is

270294 A small coin is placed on a flat horizontalturn table. The turn table is observed to make three revolutions in \(3.14 \mathrm{sec}\). What is the coefficient of static friction between the coin and turn table if the coin is observed to slide off the turn table when it is greater than \(10 \mathrm{~cm}\) from the centre of turn table
