Which one of the following is not attracted or repelled by charged objects?
a. |
protons |
b. |
photons |
c. |
electrons |
d. |
Beta particles |
Ans : (b) -Photons
Please see the explanation below.
To be attracted or repelled by a charged particle, the object/particle in consideration should also be charged. If both are like charges they repel each other and if the charges are unlike they attract each other.
Given options are:
i) Protons - Protons are the basic positve charges, so they are attracted by negative charges and repelled by positive charges.
ii) Photons - are the energy packets.They are basically particles representing a quantum of light or any electromagnetic radiation. A photon carries energy of the wave. So it is not charged.
iii) Electrons - are basic negative charged particles.
iv) Beta particles - are high energy charged particles. They may be electrons or positrons. A positron is a particle with positve charge that is same in magnitude as that of electron and has same mass as electron.
So we see that only photons are the particles among the given options that are electrically neutral.
