The magnitude of the electric force exerted on a charge in an electric field is given by

F=qE

where

q is the charge

E is the magnitude of the electric field


In this problem, we have a charge of q=6.0 \cdot 10^{-4} C, while the force exerted on it is F=4.5 \cdot 10^{-4}N, so we can rearrange the previous formula to calculate the magnitude of the electric field:

E=\frac{F}{q}=\frac{4.5 \cdot 10^{-4} N}{6.0 \cdot 10^{-4} C}=0.75 N/C

Field strength = force / charge (E=F/Q)
 E = 4.5×10^-4 / 6.0×10^-4 to obtain .....

Time = (distance) / (speed)

Time = (180 miles) / (60 mi/hr)

Time = (180/60) (mi-hr/mi)

How hydrogen and helium atoms diffrent
Rama09 [41]

Hydrogen has one proton whereas helium has two protons in its nucleus.

<h3>How hydrogen and helium atoms different from one another?</h3>

Atoms of hydrogen have a single proton in their nucleus and a single electron in the lowest energy level while on the other hand, Helium atoms have two protons in the nucleus  and two electrons in the lowest energy level. In this way, we can say that the atomic number of hydrogen is 1 whereas the atomic number of helium is 2 because of the presence of two protons. Hydrogen atom has no neutron while on the other hand, the helium atom has one neutron in its nucleus.

So we can conclude that Hydrogen has one proton whereas helium has two protons in its nucleus.
