Question

The charges

q1 = 2.2 ✕ 10−7 C,

q2 = −5.5 ✕ 10−7 C,

and

q3 = −1.2 ✕ 10−7 C

are placed at the corners of the triangle shown below. What is the force on

q1

(in N)?

Step 1

Step-1

To determine: The net force acting on the charge q1.

Given information: The amount of charges q1, q2 and q3 are given.

Step 2

Formula used:

To find the net force on charge q1 we use the coulombs law. According to this law the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.

Here, q and Q are two point charges, r is the distance between them and k is the coulomb constant.

Step 3

**Step-3:**

**Calculation:**

Using Equation-1 to find the force acting on q1.

Force acting between charge q1 and q2 is F12

Force acting between q1 and q3 is F13.

As q1 is a positive charge but q2 and q3 are negative changes...
