-
A man inside an artificial satellite feels weightlessness because the force of attraction due to earth is
-
- zero at that place
- is balanced by the force of attraction due to moon
- equal to the centripetal force
- non-effective due to particular design of the satellite
- zero at that place
Correct Option: A
Earth attracts all bodies towards its centre. The acceleration produced in the body due to attraction force of earth on it is called the acceleration due to gravity. A astronaut in a satellite experiences weightlessness because two forces act on him: gravitational pull and centrifugal force which cancel out each other with the resultant force acting on him being zero.
