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.

A cord of length 64 m is used to connected a 100 kg astronaut to spaceship whose mass is much larger than that of the astronuat. Estimate the value of the tension in the cord. Assume that the spaceship is orbiting near earth surface. Assume that the spaceship and the astronaut fall on a straight line from the earth centre. the radius of the earth is 6400 km .

A cord of length 4 m is used to connect a 100 kg astronaut to spaceship whose mass is much larger than that of the astronaut. Estimat the value of the tension in the cord. Assume that the spaceship is orbiting near earth surface. A ssume that the spaceship and th eastronaut fall on a straight line from the earth centre. The radius of the earth is 6400 km.

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. [Acceleration due to gravity on the surface of [ Earth =9.8m//s^(2) ]

An astronaut orbiting in a spaceship round the earth has a centripetal acceleration of 2.45 m//s^(2) . The height of spaceship from earth's surface is ( R =radius of earth)

An astronaut of mass m is working on a satellite orbitting the earth at a distance h from the earth's surface the radius fo the earth is R while its mass is M the gravitational pull F_(G) on the astronaut is

(a) Assuming the earth to be a sphere of uniform density, calculate the value of acceleration due to gravity at a point (i) 1600 km above the earth, (ii) 1600 km below the earth, (b) Also find the rate of variation of acceleration due to gravity above and below the earth's surface. Radius of earth =6400 km, g 9.8 m//s^(2) .

A mass of 0.5 kg is wheighd on abalance at the top of a tower 20 m high. The mass is then suspended from the pan of the balance by afine wire 20 m long and is reweighd. Find the change in weight. Assume that the radius of the earth is 6400 km

An astronaut weighs 70 kg on the earth. If he is inside a satellite revolving in circular orbit around the earth at the height of 3200 km, he would weight " " (Radius of earth = 6400 km)
