The formula to calculate the Charge Force (CF) is:
\[ CF = E \times q \]
Where:
Charge force is the force exerted on a charged particle in an electric field. It is calculated by multiplying the electric field strength by the charge of the particle. This concept is fundamental in electromagnetism and helps in understanding the behavior of charged particles in electric fields.
Let's say the electric field strength (E) is 100 N/C, and the charge point (q) is 0.5 C. Using the formula:
\[ CF = 100 \times 0.5 = 50 \, \text{N} \]
So, the charge force (CF) is 50 N.
