Thank you for the opportunity to help you with your question!

DATA:

mass = 94kg

height= 1.96106m

potential energy=?

magnitude of gravitational force=?

SOLUTION:

a)POTENTIAL ENERGY
P.E=mgh

    = (94) (9.8) (1.96106)

   = 1.8065 J

b) GRAVITATIONAL FORCE

F=GMm/r2

F= (6.67*10-11)(5.97*1024)(94)/(6.38*106)2

F= 9.1958N


Please let me know if you need any clarification. I'm always happy to answer your questions.
