Options

  1. AA particle of mass m is projected with a velocity v = k V _ e ( k < 1 ) from the surface of the earth ( V _ e = escape
  2. BA particle of mass m is projected with a velocity v = k V _ e ( k < 1 ) from the surface of the earth ( V _ e = escape
  3. CA particle of mass m is projected with a velocity v = k V _ e ( k < 1 ) from the surface of the earth ( V _ e = escape
  4. DA particle of mass m is projected with a velocity v = k V _ e ( k < 1 ) from the surface of the earth ( V _ e = escape

Correct answer

C. A particle of mass m is projected with a velocity v = k V _ e ( k < 1 ) from the surface of the earth ( V _ e = escape

Step-by-step solution

All the graphs below are intended to represent the same motion. One of them does it incorrectly. Pick it up.
The graph 33 initial slope is zero which is not possible since the initial velocity is non-zero in all other three graphs.
