ON20 P41 Q1 Gravitational Field At Surface | October/November 2020 | Cambridge A Level Physics
9702/41/O/N/20: (a) (i) State what is meant by a field of force. (ii) Define gravitational field strength. #9702w20p41 #A2gFieldP4 #Lv2 (b) An isolated planet may be assumed to be a uniform sphere of radius 3.39 × 10^6m with its mass of 6.42 × 1023 kg concentrated at its centre. Calculate the gravitational field strength at the surface of the planet. (c) Calculate the height above the surface of the planet in (b) at which the gravitational field strength is 1.0% less than its value at the surface of the planet.
