What are the exchange particles for the operation of (i) strong nuclear forces (ii) weak muclear forces ?

Explanation

To answer the question about the exchange particles for strong and weak nuclear forces, we can break it down into two parts:

### Step 1: Identify the exchange particle for strong nuclear forces
The strong nuclear force is primarily mediated by particles called **gluons**. Gluons are the exchange particles that hold quarks together within protons and neutrons, and they also bind protons and neutrons together in atomic nuclei.

### Step 2: Identify the exchange particle for weak nuclear forces
The weak nuclear force is mediated by **W and Z bosons**. These particles are responsible for processes like beta decay in nuclear reactions. The W bosons come in two varieties: W+ and W-, while the Z boson is neutral.
