WHAT IS THE SPEED OF MOON AROUNG SUN COMPARED TO THAT OF EARTH AROUND SUN? WHAT IS THE RATIO OF DECREASE OF ACCELERATION DUE TO GRAVITY WITH HEIGHT TO THAT WITH DEPTH? TWO PARTICLES OF MASSES 0.2kg AND 0.8kg are SPARATED BY 12cm.AT WHICH POINT FROM 0.2kg PARTICLE IS GRAVITAIONAL FIELD INTENSITY DUE TO 2 PARTICLES IS 0.

Expert Answer:

The acceleration due to gravity varies with height and depth as
 
 
Hence, g decreases with height by a factor (1-2h/RE) and it decreases with depth by a factor (1-d/RE)
 
Hence, the ratio is
