Physics A Level question about satellites?
Explorer 38 has a mass of 200kg and circles the earth in orbit 1.5 times the radius of the earth. Taking g=9.8N/kg on the surface and no other information, use ratios to calculate the force in Newtons pulling on the satellite when placed in this orbit.
HELP PLEASE

You have to bend the rules a bit (ignore the satellite mass) to firstly find the theoretical g at 1.5 * the earths radius from :
g = ( 1 ² / 1.5 ² ) * 9.8 = 4.3555 (m/s)/s
Force = mass * g = 200 * 4.3555 = 871.111 N

Have a think and then at least have a go at answering it
Homework is for YOU to think about and try to work out, not for you to copy other peoples answers
