Question

A particle of mass m is thrown upwards from the
surface of the earth, with a velocity u. The mass and
the radius of the earth are, respectively, M and R.
G is gravitational constant and g is acceleration due
to gravity on the surface of the earth. The minimum
value of u so that the particle does not return back
to earth, is?​

Answer 1

Answer:

particle of mass m is thrown upwards from the

surface of the earth, with a velocity u. The mass and

the radius of the earth are, respectively, M and R.

G is gravitational constant and g is acceleration due

to gravity on the surface of the earth. The minimum

value of u so that the particle does not return back

to earth, is?
