Question

c. We now place at B a point charge $q_2 = 6 \times 10^{-10} C$. 1- Calculate the electric force exerted by $q_1$ on $q_2$. 2- Is this force repulsive or attractive? Justify. Second Exercise (8 marks) A point charge $q_1 = 9nC$ is placed at the origin O. Another point charge $q_2 = 4nC$ is placed on the x-axis at point C (x = +20 cm). a. Calculate the electric fields $E_1$ and $E_2$ created respectively by $q_1$ and $q_2$ at point M of abscissa x = +7 cm.

Step 1

To calculate the electric force exerted by q on q, we can use Coulomb's Law. Coulomb's Law states that the electric force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance Show more…
