The formula to calculate the Force (F) is:
\[ F = Q \times E \]
Where:
This conversion is based on Coulomb’s Law, which states that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It is used to calculate the force in Newtons from the electric charge in Coulombs.
Let's say the electric charge (Q) is 5 Coulombs, and the electric field strength (E) is 10 N/C. Using the formula:
\[ F = 5 \times 10 = 50 \]
So, the force (F) is 50 Newtons.
Formula: \( F = k_e \frac{q_1 q_2}{r^2} \)
Example: \( F = 8.99 \times 10^9 \frac{(1 \times 10^{-6})(2 \times 10^{-6})}{0.05^2} \)
Formula: \( E = \frac{F}{q} \)
Example: \( E = \frac{10}{2 \times 10^{-6}} \)
Formula: \( 1 \, \text{V/m} = 1 \, \text{N/C} \)
Example: \( 5 \, \text{V/m} = 5 \, \text{N/C} \)
Formula: \( F = m \times a \)
Example: \( F = 10 \times 9.8 \)
Formula: \( Q = I \times t \)
Example: \( Q = 2 \times 5 \)
