Figure shows a rectangular copper plate with is centre of mass at the origin $ O $ and side $ AB = 2BC = 2 m $ . If a quarter part of the plate (shown as shaded) is removed, the centre of mass of the remaining plate would lie at
A small satellite is in elliptical orbit around the earth as shown in figure. $ L $ denotes the magnitude of its angular momentum and $ K $ denotes its kinetic energy. If $ 1 $ and $ 2 $ denote two positions of the satellite, then
One end of massless spring of spring constant $ 100 \,N/m $ and natural length $ 0.49\, m $ is fixed and other end is connected to a body of mass $ 0.5 \,kg $ lying on a frictionless horizontal table. The spring remains horizontal. If the body is made to rotate at an angular velocity of $ 2 $ rad/s, then the elongation of the spring will be
The graphs below show the magnitude of the force on a particle as it moves along the positive $ X $ -axis from the origin to $ X - X_{1} $ . The force is parallel to the $ X $ -axis and conservative. The maximum magnitude $ F_{1} $ has the same value for all graphs. Rank the situations according to the change in the potential energy associated with the force, least (or most negative) to greatest (or most positive).
A man throws a ball of mass $ 3.0\, kg $ with a speed of $ 5.0 \,m/s $ . His hand is in contact with the ball for $ 0.2 \,s $ . If he throws $ 4 $ balls in $ 2 $ seconds, the average force exerted by him in $ 1 $ second is
Figure represents the position-time graph of a body of mass $ 4 \,kg $ . Impulse $ (kg\, ms^{-1}) $ imparted to the body at $ t = 0 $ is
A particle of mass $ m $ is moving with a constant velocity along a line parallel to the positive direction of $ X $ -axis. The magnitude of its angular momentum with respect to the origin
