A judo fighter in order to throw his opponent on the mat tries to initially bend his opponent and then rotate him around his hip.
As the mass of the opponent is brought closer to the fighter's hip, the force required to throw the opponent is reduced.

A

If both assertion and reason are true and reason is the true explanation of assertion.

B

If both assertion and reason are reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A

(a) The judo fighter in order to throw his opponent on the mat tries to initially bend his opponent and then rotate him around his hip because by doing this the weight of opponent is made to pass through the hip of judo figther to make its torque zero. Hence, option (a) is true.

Galileo was punished by the Church for teaching that the sum is stationary and the earth moves around it. His opponents held the view that the earth is stationary and the sun moves around it. If the absolute motion has no meaing,are the two view points not equally correct or equally wrong?

Two children A and B of same mass (including their caps) M are sitting On a see-saw as shown in Fig. Initially, the beam is horizontal. At once, child B throws away his cap (mass M/25 ) which falls at point Q , midpoint of the left half of the beam, due to this the balance of beam is disturbed. To balance it again what is the mass in required to be put at point P on the right half of the beam?

Answer the following: a) The casing of a rocket in flight burns up due to friction. At whose expense is the heat required for burning obtained? The rocket or the atmosphere? b) Comets move around the sun in highly elliptical orbits. The gravitational force on the comet due to the sun is not normal to the comet's velocity in general. Yet the work done by the gravitatonal force over every complete orbit of the comet is zero. Why? c) An artificial satellite orbiting the earth in very atmosphere loses its energy grdually due to dissipation against atmospheric resistance, howerver small. Why then does its speed increase progressively as it comes closer and closer tothe earth? d)In fig i) the man walks 2m carrying a mass of 15 kg on his hands. In Fig ii) he walks the same distance pulling the rope behind him. The rope goes over pulley, and a mass of 15 kg hangs at its other end. In which case is the work done greater?
