Question

there are four more question that i need help setting itup...       1. what is the acceleration ofgravity 2250 km above the Earth's surface?           2. how far above the Earth'ssurface would you have to go for your weight to be reduced toone-sixth of what it is on the Earth's surface? 3. compute the force of gravity between two .3kg masses whosecenters are 1.5 meters apart. the gravitational force between two spheres is 2 x 10-8 N.there centers are 105 cm apart. the smaller sphere has a mass of8.2 kg. find the mass of the larger sphere. i really need help with these kind of questions. i kind ofhaving a hard time dealing with these kind... there are four more question that i need help setting itup...       1. what is the acceleration ofgravity 2250 km above the Earth's surface?           2. how far above the Earth'ssurface would you have to go for your weight to be reduced toone-sixth of what it is on the Earth's surface? 3. compute the force of gravity between two .3kg masses whosecenters are 1.5 meters apart. the gravitational force between two spheres is 2 x 10-8 N.there centers are 105 cm apart. the smaller sphere has a mass of8.2 kg. find the mass of the larger sphere. i really need help with these kind of questions. i kind ofhaving a hard time dealing with these kind...

Explanation / Answer

Given :
   Gravitatioanl constant ( G ) = 6.675 *10-11 N.m2/kg2          F = 1 N    mass ( m1 ) = 1 kg           m2 = 2 kg distance ( r ) = ? As we know that      Gravitational force ( F ) = G m1 m2 /r2           r = G m1 m2 / F             = ----- m    Solve it           r = G m1 m2 / F             = ----- m    Solve it
