The escape velocity of a body from the surface of earth isA. `sqrt2`B.

1.	The escape velocity of a body from the surface of earth isA. `sqrt2`B. `1/sqrt2`C. 1D. 6
Answer» Correct Answer - B According to question and by using COME`-(GMm)/(R+R)+(1)/(2)m(fv)^(2)=0+0` `impliesfvsqrt((GM)/(R)) but v=sqrt((2GM)/(R))` Therefore `fsqrt((GM)/(R))but v=sqrt((2GM)/(R))impliesf=(1)/sqrt2`
