Answer 1

Answer:

3.4×10⁻² ms⁻²

Explanation:

$centripetal \ acceleration \ \ a_c = \frac{v^2}{R}$

here,  v² $=(\frac{2\times\pi\times R}{t} )^2=\frac{4\times\pi^2\times R^2}{t^2}$

t = 1 day = 24 hours = 24×3600 s = 86400 s

centripetal acceleration , $\frac{v^2}{R} =\frac{4\times\pi^2\times R}{t^2}$ = $\frac{4\times \pi^2\times6.4\times10^6}{86400^2}$ = 3.4×10⁻²
