Question

12 Two point charges q1 and q2 are placed close to
each other . What is the nature of the force between
the charger when. (i) q1q2<0 (ii)q1q2>0​

Answer 1

Answer:

1st attractive since product less than zero means one should be negative 2nd option is repulsive greater than zero so both charge are similar nature

Answer 2

Answer:

$\large\boxed{\sf{(i)\: Attractive}}$

$\large\boxed{\sf{(ii)\: Repulsive}}$

Explanation:

It's being given that,

Two point charges q1 and q2 are placed close to each other.

Now, to find the nature of force between them.

(i) q1q2 < 0

• When their product is less than zero.
• It means that one of the charges is positive and another one is of negative nature.
• Now, we know that, unlike charges attract each other.
• Hence, the force will be attractive in this case.

(ii) q1q2 > 0

• When their product is greater than zero.
• It means that both charges are of same nature, either positive or negative.
• Now, we know that, like charges repel each other.
• Hence, the force will be repulsive in this case.
