363143 The elevator shown in figure is descending, with an acceleration of \(2\;m{s^{ - 2}}\). The mass of the block \(A\) is \(0.5\,kg\) and the mass of the block \(B\) is \(1\,kg\). The force exerted by the block \(A\) on the block \(B\) is (Take \(g = 10\;m{s^{ - 2}}\) )

363144 A block is kept on a frictionless inclined surface with angle of inclination \('\alpha '\) The incline is given an acceleration ‘\(a\)’ to keep the block stationary. Then \(a\) is equal to

363145 Assertion :
A body of mass \(1\;kg\) is making \(1\,rps\) in a circle of radius \(1\;m\). Centrifugal force acting on it is \(4 \pi^{2} N\).
Reason :
Centrifugal force is given by
\(F=\dfrac{m v^{2}}{r}\).

363146 Inside a horizontally moving box, an experiment finds that when an object is placed on a smooth horizontal table and is released, it moves with an acceleration of \(10\;m{\rm{/}}{s^2}\). In this box if \(1\;kg\) body is suspended with a light string, the tension in the string in equilibrium position (\(w.r.t.\) experimenter) will be (Take \(g = 10\;m{\rm{/}}{s^2}\))
