massless dance floor. Sally looks up and she sees Tom. She feels an attraction. If the attraction is gravitation, find its magnitude. Assume both can be replaced by spherical masses and that the gravitational constant is 6.67259 × 10^(−11)N · m^2/kg^2.
Answer in units of N
Answer in units of N
-
F = G(m1m2/r^2)
*mass stays in Kg, G = 6.67259 × 10^(−11)m^3/kg.s^2
= 6.67259 × 10^(−11)(43.4*69.9/30.5^2)
= 2.176x 10^-10 N
*mass stays in Kg, G = 6.67259 × 10^(−11)m^3/kg.s^2
= 6.67259 × 10^(−11)(43.4*69.9/30.5^2)
= 2.176x 10^-10 N
