Coloumbs Laws and electric fields

In summary, we are trying to determine the acceleration of a proton with a charge of +e and a mass of 1.67 E-27 in an electric field with an intensity of 500 N/C. This can be calculated using the formula f = q*e, where f is the force, q is the charge, and e is the electric field. We also know that force is equal to mass times acceleration, so we can use this information to solve for acceleration. The charge, q, in this case is the charge of an electron, as shown in a useful table of constants.

Determine the acceleration of a proton (q = +e, m = 1.67 E -27)
in an electric field of intensity 500 N/C. How many times is this acceleration greater then that due of gravity

I'm not so understanding on todays lessons
teh 2 formulas I can recall are f = q*e
and e = f/q
but i don't see that helping here, can someone help me start off
thanks guys.

HINT: Force = mass x acceleration

yup i knew of that
i got mass, I am looking for acceleration
but what's force
f = q * e right
i got e just don't know what q is (what they mean by q = +e)

FAQ: Coloumbs Laws and electric fields

What is Coloumbs Law?

Coloumbs Law is a fundamental law in physics that describes the relationship between electric charges. It states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

How is Coloumbs Law used to calculate electric force?

To calculate the electric force between two charged objects, we use the equation F = (k * q1 * q2) / r2, where F is the force, k is the constant of proportionality (9 x 10^9 N*m^2/C^2), q1 and q2 are the charges of the two objects, and r is the distance between them.

What is an electric field?

An electric field is a region in space where an electric charge experiences a force. It is represented by electric field lines which show the direction and strength of the electric field.

How is the strength of an electric field calculated?

The strength of an electric field is calculated using the formula E = F/q, where E is the electric field strength, F is the force experienced by the test charge, and q is the magnitude of the test charge.

How do electric fields affect the motion of charged particles?

Electric fields exert a force on charged particles, causing them to accelerate in the direction of the field if they are positive or opposite the direction of the field if they are negative. This can result in the particles moving in a curved path or changing their speed.
