Question 1 attached.Question 2) A space probe was launched to perform a surface study of Venus. The probe's average orbital radius (distance from the centre of Venus) was 6.79 X 10^6 m. The mass of Venus is 4.88 X 10^24 kg. The average gravitational field strength of Venus at this distance is:A. 7.06 X 10^6 N/kgB. 4.79 X 10^10 N/kgC. 4.79 X 10^7 N/kgD. 7.06 N/kgQuestion 3) Use the following information to answer the next question.
