Physics Question from JEE Main 2023 · 11 April, Shift 2

A space ship of mass 2×104 kg2 \times 10^4 \, \text{kg} is launched into a circular orbit close to the earth surface. The additional velocity to be imparted to the space ship in the orbit to overcome the gravitational pull will be (if g=10 m/s2g = 10 \, \text{m/s}^2 and radius of earth = 6400 km6400 \, \text{km}):

  • A

    7.9(2−1) km/s7.9(\sqrt{2}-1) \, \text{km/s}

  • B

    7.4(2−1) km/s7.4(\sqrt{2}-1) \, \text{km/s}

  • C

    11.2(2−1) km/s11.2(\sqrt{2}-1) \, \text{km/s}

  • D

    8(2−1) km/s8(\sqrt{2}-1) \, \text{km/s}
