Unlike the neutron the (charged) proton has an extra 2 MeVc^-2 (roughly) associated with its electrical energy. This extra energy should make it heavier than the neutron...so why is the

neutron heavier than the proton?

Context : nuclear physics

Pls show full working and thank you.

Expert Solution

A neutron is a neutral particle which have equal positive and negative charge.

When we remove an electron from neutron then only positive charge remains on it , and due to this charge it has self electrical energy of 2 MeV.

This is not possible to convert a neutron to proton by adding positive charge because smallest positive charge is proton itself which is made by removing a electron from a neutron.

So a proton is always lighter than a neutron by the mass of a electron.

It is not possible to convert a proton to neutron by removing positive charge.

We have to add a electron to proton to convert it into neutron.

NBM has $2 million of extra cash. It has two choices to make use of the cash. One alternative is to invest the cash in financial assets. The resulted investment income will be paid out as a special dividend at the end of three years. In this case, the firm can invest in Treasury bills yielding 7%, or an 11% preferred stock. The tax law says only 30% of the dividend from the preferred stock investment would be subject to...

2. Suppose that the treasurer of IBM has an extra cash reserve of USD100,000,000 to invest for six months. The annual interest rate is 4% in the United States and 3% in Germany. The spot exchange rate EUR/USD is 0.94 and the six-month forward exchange rate EUR/USD is 0.92. The treasurer of IBM does not wish to bear any exchange risk. Should he invest in US or in Germany to maximize the return? How much will his proﬁt and return...
