Question

Charges q1=-9q and q2= 2q are located at x=-a and x= a , respectively. What is the value of q1 and q2?

1) q1 = -9q, q2 = 2q
2) q1 = 9q, q2 = -2q
3) q1 = -2q, q2 = 9q
4) q1 = 2q, q2 = -9q

Answer 1

The values of q1 and q2 are q1 = -9q and q2 = 2q.

This correct answer is 1)

Step-by-step explanation:

Certainly, let's break down the information given and explain why the correct answer is q1 = −9q and q2 = 2q.

The problem states that there are two charges, q1 and q2, located at specific positions on the x-axis:

Charge q1 :

Located at x=−a

The value of q1 is given as −9q.

This means that there is a charge q1 at a position x equal to the negative of a, and the magnitude of this charge is 9 times the magnitude of some charge q, with the negative sign indicating the direction of the charge.

Charge q2:

Located at x=a

The value of q2 is given as 2q.

This means that there is a charge q2 at a position x equal to a, and the magnitude of this charge is 2 times the magnitude of some charge q.

Therefore, the correct answer is:

q1 =−9q,q2=2q

This correct answer is 1)
