| Directions: In the following questions, a statement of Assertion (A) is followed by a statement of Reason: |
| (R). Mark the correct choice as: |
| Assertion (A): If a proton and an electron are placed in the same uniform electric field. They experience different acceleration. |
| Reason (R): Electric force on a test charge is independent of its mass. |
A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
B) Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
C) Assertion (A) is true but Reason (R) is false
D) Assertion (A) is false and Reason (R) is also false
Correct Answer: B
Solution :
(b) Electron and proton have same amount of charge so they have same Coulomb force. They have different accelerations because they have different masses \[\left( a=\frac{F}{m} \right)\].
