Consider three masses \(M_{1}, M_{2}\) and \(M_{3}\left(M_{1}>\right.\) \(M_{2}>M_{3}\) ) are at rest on a horizontal plane as shown in the figure. Now the angle of inclination \((\theta)\) of the plane is gradually increased until the masses just begin to slide. (Assume the co-efficient of static friction between the masses and the surface is constant).
Then the correct statement of the following is

A box of mass \(2 \mathrm{~kg}\) is placed on a inclined plane that makes \(30^{\circ}\) with the horizontal. The coefficient of friction between the box and inclined plane is 0.2 . A force \(F\) is applied on the box perpendicular to the incline to prevent the box from sliding down. The minimum value of \(F\) is(acceleration due to gravity \((\mathrm{g})=10 \mathrm{~ms}^{-2}\) )
371959 The coefficient of static friction between the road and tyres of a car is 0.4 . The maximum permissible speed of the car is \(10 \mathrm{~ms}^{-1}\) on curved unbanked road. Then the maximum radius of curvature of the road is (acceleration due to gravity \(=10 \mathbf{m s}^{-2}\) )
