Even though an electric field `vecE` exerts a force `qvecE` on a charged particle yet the electric field of an EM wave does not contribute to the radiation pressure (but transfer energy). Explain.

Explanation

To understand why the electric field of an electromagnetic (EM) wave does not contribute to radiation pressure, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Electric Field and Force**:
- An electric field \( \vec{E} \) exerts a force \( \vec{F} = q \vec{E} \) on a charged particle, where \( q \) is the charge of the particle. This force can cause the charged particle to accelerate.

2. **Nature of Electromagnetic Waves**:
