Question

Time period of planet around the sun is 11.6 years how far is the planet from the sun if the distance between sun and earth is 1.5 into 10 ki power 8 kilometres

Answer 1

Time period of planet around the sun is 11.6 years how far is the planet from the sun if the distance between sun and earth is 1.5 into 10 ki power 8 kilometres

We assume here the speed of planet = Same as speed of Earth

Distance covered by Earth in a Year = $2\pi R$ km

R = 1.5 × 10⁸ km

Distance covered by Earth in 11.6 Years = $11.6 \times 2\pi R$ km

Let say distance of Another planet from Sun = X km

Then Distance covered by that planet in 11.6 Years = $2\pi X$ km

Equating both

11.6 R = X

=> X = 11.6 R

=> X = 11.6 × 1.5 × 10⁸

=> X = 17.4 × 10⁸

=> X = 1.74 × 10⁹ kM

Answer 2

Answer:

Tp = 11.6 year rp = ?

Te = 1 year re = 1.5 x 10 11 m

Or

=7.68 x 10 11 m.
