Two astronauts A and B connected with a ...

Two astronauts A and B connected with a rope stay stationary in free space relative to their spaceship. Mass of A is more than that of B and the rope is straight. Astronaut A statas pulling the rope but astronaut B does not. If you were the third astronaut in the spaceship, what do you observe?

Astronaut B accelerates towards A and A remains stateionery.

Both accelerate towards each other with equal accelerations of equal modulus.

Both accelerate towards each other but acceleration of B is greater than that of A.

Both accelerate to wards each other but acceleration of B is smaller than that of A.

A chord of length 64m is used to connect a 100 kg astronaut to a spaceship whose mass is much larger than the that of the astronaut. Estimate the value of tension in the cord. Assume that the spacehip is orbiting near the earth surface. Also assume that the spaceship and hte astronaut fall on strainght line from the earth's centre. The radius of he earth 6400km.

Two fat astronauts each of mass 120 kg are travelling in a closed spaceship moving at a sped of 15 km/s in the outer space far remvoed from tall other material objects. The total mass of the spaceship and its contents including the stronauts is 660 kg. If the astronuts do slimming exercise and thereby reduce theri mases to 90 kg, each with wht velocity will spaceship move?

A spaceship is orbiting the earth in a circular orbit at a height equal to radius of the earth (R_(c) = 6400 km) from the surface of the earth. An astronaut is on a space walk outside the spaceship. He is at a distance of l = 200 m from the ship and is connected to it with a simple cable which can sustain a maximum tension of10 N. Assume that the centre of the earth, the spaceship and the astronaut are in a line. Mass of astronaut along with all his accessories is 100 kg. Do you think that a weak cable that can only take a load of 10 N, can prevent him from drifting in space ? Make a guess. Estimate the tension in the cable.
