A planet is revolving around the Sun as shown in the figure. The radius vectors joining the Sun and the planet at points $A$ and $B$ are $90 \times 10^{6} km$ and $60 \times 10^{6} km$, respectively. The ratio of velocities of the planet at the points $A$ and $B$ when its velocities make angle $30^{\circ}$ and $60^{\circ}$ with major-axis of the orbit is
A car is traveling along a curved road of radius r. If die coefficient of friction between the tyres and the road is $ \mu $ , the car will skid if its speed exceeds
Two particles A and B initially at rest move towards each other under a mutual force of attraction. At the instant when the velocity of A is v and that of B is 2v. The velocity of centre of mass of the system is
A light rod of length 100 cm is suspended from the ceiling horizontally by means of two vertical wires of equal lengths tied to the ends of the rod. One of the wires is made of steel and is of area of cross- section $ 0.1\text{ }c{{m}^{2}}. $ The other wire is of brass and of area of cross-section $ 0.2\text{ }c{{m}^{2}}. $ The position from the steel wire along the rod at which a load is to be placed to produce equal stresses in both wires is ( $ {{Y}_{steel}}=20\times {{10}^{11}} $ dyne $ c{{m}^{-2}};\text{ }({{Y}_{brass}}=10\times {{10}^{11}}dyne\text{ }c{{m}^{-2}}) $
A square plate of 0.1 m side moves parallel to a second plate with a velocity of 0.1 m/s, both plates being immersed in water. If the viscous force is 0.002 N and the coefficient of viscosity is 0.01 Poise, distance between the plates in metre is:
A boy of mass 50 kg is standing on a weighing machine placed at the floor of a lift. The machine reads his weight in newtons. What is the reading of the machine, if the lift is moving Upwards with a uniform Speed of $ 10\text{ }m{{s}^{-1}}. $ $ (g=10m{{s}^{-2}}) $
