Calculating Distance AB and Charge Q
Electric field intensity is given by the equation E = kQ/r^2, where k is the electrostatic constant, Q is the charge, and r is the distance between the point charge and the point where the field is being measured.
Finding the Distance AB
Given that the electric field intensity at point B due to the charge Q at point A is 24 N/C, we can write:
24 = kQ/AB^2
Similarly, the electric potential at point B due to the charge Q at point A is given by V = kQ/AB.
Given that the electric potential at point B is 12 J/C, we have:
12 = kQ/AB
Dividing the two equations, we get:
24/12 = AB^2/AB
AB = 2
Therefore, the distance AB between point A and point B is 2 units.
Finding the Magnitude of Charge Q
Now that we know the distance AB, we can find the magnitude of charge Q by substituting back into one of the equations. Let's use the equation for electric potential at point B:
12 = kQ/2
Q = 24/k
Since k is a constant (8.99 x 10^9 Nm^2/C^2), we can calculate the magnitude of the charge Q:
Q = 24/(8.99 x 10^9)
Q ≈ 2.67 x 10^-9 C
Therefore, the magnitude of the charge Q is approximately 2.67 x 10^-9 C.
Electric field intensity is given by the equation E = kQ/r^2, where k is the electrostatic constant, Q is the charge, and r is the distance between the point charge and the point where the field is being measured.
Finding the Distance AB
Given that the electric field intensity at point B due to the charge Q at point A is 24 N/C, we can write:
24 = kQ/AB^2
Similarly, the electric potential at point B due to the charge Q at point A is given by V = kQ/AB.
Given that the electric potential at point B is 12 J/C, we have:
12 = kQ/AB
Dividing the two equations, we get:
24/12 = AB^2/AB
AB = 2
Therefore, the distance AB between point A and point B is 2 units.

Now that we know the distance AB, we can find the magnitude of charge Q by substituting back into one of the equations. Let's use the equation for electric potential at point B:

Q = 24/(8.99 x 10^9)
Q ≈ 2.67 x 10^-9 C
Therefore, the magnitude of the charge Q is approximately 2.67 x 10^-9 C.
