Three masses are placed along the x-axis: m1 = 3.2 kg is a distance x1 = 0.43 m to the left of the origin, m2 = 3.6 kg is a distance x2 = 0.31 m to the right of the origin, and m3 = 4.1 kg is a distance x3 = 0.47 m to the right of the origin. system of masses 1) What is the location of the center of mass of the system?

0.153 meters to the right of the origin.

Explanation:

The location of the center of mass of a particle system is given by this formula:

The current inputs are presented below (It is assumed that distances are positive for all number to the right of the origin:

Then, the location is finally found:

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
