I need to turn this in quickly :((

F = 6.0 x 10⁻⁸ N

Given

mass of 2 dump trucks = 1500 kg

distance = 50 m

Required

Gravitational force

Solution

Newton's Gravity Law:  

with F = gravitational force,  

G = gravitational constant,  

m1, m2 = mass of object,  

r = distance between two objects.  

Input the value :

F = (6.67.10⁻¹¹N.m² / kg² x 1500²) :  50²

F = 6.0 x 10⁻⁸ N

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
