As we know, Kepler's Law of Period states that, if R is orbital radius and T is time period then:-

 :\implies\sf\red {{T^2\propto R^3}}

Therefore,

:\implies\sf{\left(\dfrac{T_1}{T_2}\right)^2=\left(\dfrac{R_1}{R_2}\right)^3}

:\implies\sf{\dfrac{T_1}{T_2}=\left(\dfrac{R_1}{R_2}\right)^{\dfrac{3}{2}}}

:\implies\sf{T_1=T_2\left(\dfrac{R_1}{R_2}\right)^{\dfrac{3}{2}}}

Here,we are given Information :-

  • \sf{R_1:R_2=4:3}

  • \sf{T_2=355\ days}

So time period of the Earth's orbit around the Sun will be :-

:\implies\sf{T_1=365\left(\dfrac{4}{3}\right)^{\dfrac{3}{2}}}

:\implies\sf{T_2=4\times 1.54\ days}

:\implies\underline{\underline\red{{\sf{T_1=561.95\ days}}}}\\\\
