What mass of protons would be required to just neutralize the charge of 1.0 g of electrons?

Mass of proton is 1837 times the mass of an electron such as:

Mass of proton = 1837 mass of electron

or

one electron = 1/1837 the proton’s mass

then  

grams of protons.

grams protons

Thus, 1.8 x 10^3 grams mass of proton is required to neutralize 1 g electron

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

they are both synthetic elements
