Question

5. A charged object is able to repel A) only charged objects

B) neutral objects and neutral particles
C) neutral objects but not neutral particles
D) only neutral particles

Answer 1

only charged objects hope you pass lol

Step-by-step explanation:

Answer 2

A) only charged objects

Step-by-step explanation:

The electrostatic force between two objects is given by

`F=k(q_1 q_2)/(r^2)`

where

k is the Coulomb's constant

q1, q2 are the charges of the two objects

r is the separation between the two objects

We have:

- If the charges have same sign (q1 and q2 have same sign), the force is repulsive

- if the charges have opposite sign (q1 and q2 have opposite sign), the force is attractive

If one of the object is neutral, its charge is zero: q=0, so the electrostatic force is also zero.

So, the correct option is

A) only charged objects

because all the other options (B, C and D) involve the presence of neutral particles, for which q=0 and so the electrostatic force is also zero.
