The magnitude of the electric force between two protons is 2.3x10-26 n. how far apart are they?
a. 0.022

To solve this problem, we make use of the Coulumb’s law which relates the electrical force to the charges. The formula used in Coulumb’s law is given as:

F = k q1 q2 / r^2

where,

F = electric force = 2.3 *  10^-26 N

k = Coulumb’s constant = 9 * 10^9 N m^2/C^2

q1 = q2 = electric charge of protons = 1.602 * 10^-19 C

r = distance between the two protons

Substituting the given values:

2.3 *  10^-26 N = (9 * 10^9 N m^2/C^2) (1.602 * 10^-19 C)^2 / r^2

r^2 = 0.01 m^2

r = 0.1 m

Therefore the protons are only 0.1 m apart or 10 cm.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
