Question 5 only

[5] #5. A solid spherical mass M1- 782 kg and radius 15.2 cm is concentric with a spherical shell M2=54.6 kg and radius 28.2 cm as shown. A point mass m = 24.2 grams is at a distance of 19.4 cm from the center of the solid sphere. Determine the magnitude of the gravitational force on mass m. Give your answer in the form "abc x 10^(x) Unit". For #6 and #7, use the figure at the right which represents two point charges Q1=+37.2 HC and Q2 =-58.2 UC, separated by a distance of 13.8 cm. Q1
