(A): Two particles of same charge projected with different velocity normal to electric field experience same force
(R ): A charged particle experiences force, independent of velocity in electric field

Options

A. Both .A. and .R. are true and .R. is the correct explanation of .A.
B. Both .A. and .R. are tru and .R. is not the correct explanation of .A.
C. A. is true and .R. is false
D. A. is false and .R. is true

Answer

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step-by-step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Two particles of the same charge projected with different velocities normal to the electric field experience the same force."
- In an electric field (E), the force (F) experienced by a charged particle (q) is given by the formula:
\[ F = qE \]
- This formula indicates that the force depends only on the charge of the particle and the strength of the electric field, not on the velocity of the particle.

2. **Understanding the Reason (R)**:
- The reason states that "A charged particle experiences force, independent of velocity in an electric field."
- This is consistent with the formula for electric force mentioned earlier. The force experienced by a charge in an electric field does not change with its velocity.

3. **Conclusion**:
- Since both the assertion and the reason are true, and the reason correctly explains why the assertion holds (because the force is independent of velocity), we conclude that both the assertion (A) and the reason (R) are true, and R is the correct explanation of A.

### Final Answer:
Both assertion (A) and reason (R) are true, and R is the correct explanation of A.
