    ASSERTION: If a proton and an electron are placed in the same uniform electric field, they experience different acceleration.
    REASON: Electric force on a test charge is independent of its mass.

    A) If both assertion and reason are true and reason is the correct explanation of assertion.

    B) If both assertion and reason are true and reason is not the correct explanation of assertion.

    C) If assertion is true but reason is false.

    D) If both assertion and reason are false.

    E) If assertion is false but reason is true.

    Correct Answer: B

    Solution :

    Electron and proton have same amount of charge so they have same Coulomb force. They have different accelerations because they have different masses \[\left( a=\frac{F}{m} \right)\]therefore, both assertion and reason are true and reason is the correct explanation of the assertion.
