Answer:
F = 3.55 x 10²² N
Explanation:
average distance of sun from earth = 1.5 × 10⁸ km
mass of earth = 6 x 10²⁴ kg
time = 365.25 days
distance = 2 π r
distance = 2 π x 1.5 x 10¹¹ m
= 3 π x 10¹¹ m
[tex]v = \dfrac{d}{t}[/tex]
[tex]v = \dfrac{3 \pi \times 10^{11}}{365.25 \times 24 \times 60 \times 60}[/tex]
v = 2.98 x 10⁴ m/s
we know centripetal force
[tex]F = \dfrac{mv^2}{r}[/tex]
[tex]F = \dfrac{6 \times 10^{24}\times (2.98\times 10^4)^2}{1.5\times 10^{11}}[/tex]
F = 3.55 x 10²² N
