The velocity of an object in a circular orbit can be calculated using the formula
$$v = G ^ { a } m ^ { b } r ^ { c }$$
where:
\(G =\) Universal constant of gravitation in \(\mathrm { Nm } ^ { 2 } \mathrm {~kg} ^ { - 2 }\)
\(m =\) Mass of the Earth in kg
\(r =\) Radius of the orbit in metres
Use dimensional analysis to find the values of \(a , b\) and \(c\) [0pt]
