the force is given by the equation

q*v*B [email protected]

thus it will be

(1.6*10^-19)*(7.8*10^4)*(3)*1/√2 which gives 2.6*10^-14 N

Formula

F = q*v*B Sin (theta)

Givens

q = 1.6*10^-19 coulombs

v = 7.8*10^4 m/s

B = 3 Tesla

phi = 45 degrees.

Solution

F = q*v*B * sin(45)

F = 1.6*10^-19 * 7.8*10^4 * 3 * Sin(45)

F = 2.6 * 10 ^-14

Why is the overall charge of the atom neutral or zero?
MrRissso [65]

Answer:

B

Explanation:

this is because the neutrons do not have a charge, the things that have charge in an atom are electrons and protons.

and in the nucleus of an atom, there are protons and neutrons so you can see that A is not the answer

if you see the periodic table, you will know that the number of electrons and protons are equal, so the charges cancel each other out, hence the charge of an atom will be neutral

let me give you a tip which I got from my teacher, never write there is no charge in the atom, this suggests that there is no protons or electrons.

instead, write, the it is neutral

hope it helps if not please report it so that someone else gets to try it out

A force of 80 N is exerted on an object on a frictionless surface for a distance of 4 meters. If the object has a mass of 10 kg,
solmaris [256]
There are two ways to find energy. Energy=F*d=mv^2. We can use this relationship to find v:
Fd=0.5mv^{2} \\ 80*4=0.5*10v^{2} \\ 64=v^{2} \\ v=8 m/s
