Question

An artificial satellite of mass 2500 kilogram is orbiting around the earth with a speed of 4 km per second -1 at a distance of 10*-4 from the Earth calculate the centripetal force action on it.

Answer 1

Data: m = 2500 kg

V= 4km

$r = {10}^{ - 4?}$

Formula=

$c.f. = \frac{?mv {}^{?2} }{?r}$

solution =

$\frac{2500 \times 4}{10 { }^{ - 4 {?}^{2?} } ?}$

$\frac{10000}{10 {}^{ - 4 {}^{2} } }$

$\frac{10000 \times 10 {}^{8} }{10 \times 10}$

${100}^{8} kg \: \: m \: \: {s}^{ - 1}$
