Assertion: If a proton and an electron are placed in the same uniform electric field.

Question

Read the assertion and reason carefully to mark the correct option out of the options given below : 

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

(b) If both assertion and reason are true but reason is not the correct explanation of the assertion. 

(c) If assertion is true but reason is false. 

(d) If the assertion and reason both are false. 

(e) If assertion is false but reason is true. 

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.

Answer 1

The correct option (b) If both assertion and reason are true but reason is not the correct explanation of the assertion.

Explanation:

If a proton & electron are placed in the same uniform electric field they experience different acceleration. 

Electric force on test charge is independent of its mass. 

Hence both statements are true. But reason is not explanation of assertion.
