Questions & Step-by-Step Solutions
If the electric field at a point is 200 N/C directed towards the positive x-axis, what is the potential difference between two points A and B separated by 3m along the x-axis?
Step 1: Understand that the electric field (E) is given as 200 N/C and it is directed towards the positive x-axis.
Step 2: Identify the distance (d) between points A and B, which is given as 3 meters along the x-axis.
Step 3: Use the formula for potential difference (V) which is V = -E * d.
Step 4: Substitute the values into the formula: V = -200 N/C * 3m.
Step 5: Calculate the result: V = -600 V.
Step 6: Interpret the result: The potential at point B is 600 V lower than at point A.
Electric Field and Potential Difference – The relationship between electric field (E) and potential difference (V) is given by V = -E * d, where d is the distance moved in the direction of the field.
