What is the charge on an object that experiences a force of 5 Newtons in an electric field of 50 Newtons per coulomb?

andrew-mc [135]

Answer:

Explanation:

F = qE

F is the force in Newtons

q is the test charge

E is the electrical field produced by the source charge

$5=q(50)\\q=1*10^-^1Coulombs$

In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which

Thepotemich [5.8K]

The number of protons that strike the tumor each second is $1.75 \times 10^8$ protons.

<u>Given the following data:</u>

Energy of proton = $2.8 \times 10^{-11}$ Joules.

Current = 84 nA to A = $84 \times 10^{-9}$ Ampere.

Energy of total dose = $3.4 \times 10^{-3}$ Joules.

<u>Scientific data:</u>

Charge of proton = $1.602 \times 10^{-19}$ C.

To determine the number of protons that strike the tumor each second:

<h3>How to determine the number of protons.</h3>

Mathematically, the quantity of charge per unit time is given by this formula:

$Q =It=Ne\\\\N = \frac{Q}{e}$

<u>Where:</u>

N is the number of protons.

t is the time measured in seconds.

I is the current.

e is the charge of protons.

Substituting the parameters into the formula, we have;

$N=\frac{2.8 \times 10^{-11} }{1.602 \times 10^{-19}} \\\\N = 1.75 \times 10^{8}$ protons.

Which type of energy is associated with electric currents?

zalisa [80]

B. Electrical energy

Among the choices given, the type of energy associated with electric currents is electrical energy. By its definition, electric current is the flow of charged particles through a conductor or a conduction medium, for example, a wire. Basically, it involves electricity. It is similar to water current but instead of water molecules, charged particles move down a conductor. These charged particles are mostly electrons which move freely and at random. When all the free electrons move in the same direction, a current is created.
