At what height h will be the value of g be half of that on the surface of earth? |
|
Answer» SOLUTION :c = `GM/R^2` ...... (1) Let the VALUE of G be g/2 at a height H above the ground. then g/2 = `(GM)/(R+h)^2 ..... (2) (1)/(2) 2 = `(R+h)^2/R^2` or `sqrt2` = R+h/R = `RSQRT2` then h = `(sqrt2 - 1)R` = 0.414R |
