A body is projected vertically upwards from the surface of the earth with a velocity equal to half of escape velocity of the earth. If `R` is radius of the earth, maximum height attained by the body from the surface of the earth isA. `(R)/(6)`B. `(R)/(3)`C. `(2R)/(3)`D. R |

Answer» Correct Answer - b `(h)/(R)=(u^(2))/(v_(e)^(2)-u^(2))=((1)/(4)v_(e)^(2))/(v_(e)^(2)-(1)/(4)v_(e)^(2))=((1)/(4)v_(e)^(2))/((3)/(4)v_(e)^(2))=(1)/(3)` `h=(R)/(3)` |
