How much work must an external force do on the satellite to move it from a circular orbit of radius 2 re to 3 re, if its mass is 2000 kg? the universal gravitational constant 6.67 × 10−11 n · m2 /kg2 , the mass of the earth 5.98 × 1024 kg and its radius 6.37 × 106 m. answer in units of j.

20872108843.53741 Joules

Explanation:

Re = Radius of Earth = 6.37×10⁶ m

M = Mass of the Earth =  5.98 × 10²⁴ kg

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

m = Mass of satellite = 2000 kg

Potential energy

Energy required to move the satellite is 20872108843.53741 Joules

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
