please just explain the ans rates assured

None

The smallest amount of electricity is carried by

deuteron means an ionized deuterium atom, so it will carry the smallest amt of charge +e

hi u r saying it will carry charge +e but an antioneutron carries 0 charge so why it is not ans

correct me if i am wrong

0 chrg means 0 current.. i think question is which has smallest.current.. but it is given tht there is current

smallest amount of electricity to be carried is the qn
ie
some amount of electricity has to be carried and it should be the least among the given options but not 0

Sol) Since current I = dq/dt

where dq = amount of charge flowing in time dt

Since all other particle in the options carry charge except anti-neutron, so correct option should be (C)

Some more information on anti neutron

The antineutron is the antiparticle of the neutron. It was discovered by Bruce Cork in 1956, a year after the antiproton was discovered. An antineutron has the same mass as a neutron, and no net electric charge. However, it is different from a neutron by being composed of antiquarks, rather than quarks. In particular, the antineutron consists of two anti-down quarks and one anti-up quark.

The magnetic moment of the antineutron is the opposite of that of the neutron. It is +1.91 µ_N for the antineutron but -1.91 µ_N for the neutron (relative to the direction of the spin). Here µ_N is the nuclear magneton.

Since the antineutron is electrically neutral, it cannot easily be observed directly. Instead, the products of its annihilation with ordinary matter are observed.

There are theoretical proposals that neutron-antineutron oscillations exist, a process which would occur only if there is an undiscovered physical process that violates baryon number conservation,

sir ans is B not antineutron as u r saying

it is a qns which had appeared in a medical entrance exam and was given in their prospectus so ans cant be wrong how ever iunderstood thanks computer
