Discuss the variation of acceleration due to gravity with altitude. Share with your friends Share 0 Decoder_2 answered this Dear student, Acceleration due to gravity on the surface of earth:g=GMR2Acceleration due to gravity at some altitude 'h' from the surface of earth:g'=GMR+h2g'g=GMR+h2GMR2 =RR+h2 =R+hR-2 =1+hR-2 =1-2hR (by neglecting higher terms in binomial expansion when h <<R)Hence,g'=g1-2hRCase I: When h is considerable compared to Rg'=gRR+h2Case II: When h is not considerable compared to Rg'=g1-2hR Regards 2 View Full Answer
