Given Information:
- Charge 1 (+2µC) at x = 0
- Charge 2 (-32 µC) at x = 60 cm
- Charge 3 (-Q) to be placed on the x-axis
Concept:
- The third charge should be placed at such a distance that the net force on it is zero.
- This can be achieved by considering the forces from the other two charges and setting them equal to zero.
Calculation:
Let's assume the distance of the third charge from the +2µC charge is x cm. Therefore, the distance from the -32 µC charge would be (60 - x) cm.
The force due to the +2µC charge on the third charge:
F1 = k * (2 * 10^-6) * Q / x^2
The force due to the -32 µC charge on the third charge:
F2 = k * (-32 * 10^-6) * Q / (60 - x)^2
For the third charge to experience no net force:
F1 = F2
k * (2 * 10^-6) * Q / x^2 = k * (-32 * 10^-6) * Q / (60 - x)^2
Solving the above equation, we get:
2 / x^2 = -32 / (60 - x)^2
x = 15 cm
Therefore, the distance of the third charge from the +2µC charge is 15 cm. Hence, the correct answer is option c) 15 cm.
- Charge 1 (+2µC) at x = 0
- Charge 2 (-32 µC) at x = 60 cm
- Charge 3 (-Q) to be placed on the x-axis
Concept:
- The third charge should be placed at such a distance that the net force on it is zero.
- This can be achieved by considering the forces from the other two charges and setting them equal to zero.
Calculation:
Let's assume the distance of the third charge from the +2µC charge is x cm. Therefore, the distance from the -32 µC charge would be (60 - x) cm.
The force due to the +2µC charge on the third charge:
F1 = k * (2 * 10^-6) * Q / x^2
The force due to the -32 µC charge on the third charge:
F2 = k * (-32 * 10^-6) * Q / (60 - x)^2
For the third charge to experience no net force:
F1 = F2
k * (2 * 10^-6) * Q / x^2 = k * (-32 * 10^-6) * Q / (60 - x)^2
Solving the above equation, we get:
2 / x^2 = -32 / (60 - x)^2
x = 15 cm
Therefore, the distance of the third charge from the +2µC charge is 15 cm. Hence, the correct answer is option c) 15 cm.
