What is the nature of force between two point charges Q1 and Q2 if a q1q2 0 B q1q2 0?

if Q1>0, then Q2 <0. So, Q1 and Q2 and opposite charges. The nature of force between them will be attractive. Opposite charges attract each other.

How do you find the magnitude of a point charge?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

What is the nature of electrostatic force between two point charges q1 and q2 if q1 q2 0?

The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative). The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative).

What is the nature of force between two charges q1 and q2 if?

The electric force between q1 and q2 is directly proportional to the product of the magnitude of charge q1 and q2 and is inversely proportional to the square of the distances between their centres.

How do you solve electric field?

The electric field E is defined to be E=Fq E = F q , where F is the Coulomb or electrostatic force exerted on a small positive test charge q. E has units of N/C. The magnitude of the electric field E created by a point charge Q is E=k|Q|r2 E = k | Q | r 2 , where r is the distance from Q.

What is the value of point charge?

If the radius of the Gaussian surface is doubled, then the flux passing through the surface remains the same i.e., −103 N m2/C. Therefore, the value of the point charge is −8.854 nC.

What can be the nature of charges q1 and q2 a q1 is positive q2 is negative B q1 is negative q2 is negative C q1 is negative q2 is positive D q1 is positive q2 is positive?

Explanation: If q1 × q2 > 0, Both q1 and q2 must be positive (or) Both q1 and q2 must be negative. Positive charges repel each other, and also negative charges repel each other. Hence the correct answer is (b) Repulsive in both the cases.
