An electric charge 10 - 6 μ C is placed at origin ( 0 , 0 ) m of X - Y co-ordinate system. Two points P and Q are situated at ( 3 , 3 ) m and ( 6 , 0 ) m respectively. The potential difference between the points P and Q will be :
Options
- A3 V
- B6 V
- C0 V
- D3 V
Correct answer
C. 0 V
Step-by-step solution
The formula to calculate the potential difference between P and Q is given by ∆ V = k q 1 r 1 - 1 r 2 . . . 1 Now, r 1 = ( 3 ) 2 + ( 3 ) 2 m = 6 m And, r 2 = ( 6 ) 2 + 0 m = 6 m As r 1 = r 2 = 6 m and the value of the charge remains constant, the potential difference between the points is zero.
