Chapter 30, Problem 76A

To determine

To calculate:

The charge of a particle is made of three up quarks.

Answer to Problem 76A

The charge of a particle made up of three up quarks is $+2e$ .

Explanation of Solution

Given:

The charge of one up quark $=\frac{+2e}{3}$

Formula Used:

Charge of a particle consist of three up quarks $=$ the charge of one up quark $\times$

(No of up quarks)

Calculation:

The charge of one up quark $=\frac{+2e}{3}$

Thus, the charge of a particle having three up quarks will be calculated by multiplying the value of charge of one up quark by $3$ ,

  $=\frac{+2e}{3}\times 3$

Reducing the similar terms from numerator and denominator,

  $=+2e$

Conclusion:

Hence, the charge of a particle composed of three up quarks is $+2e$ .
