Solution


Q.

Assertion : Convex mirrors are used for rear view on vehicles.
Reason : The size of the image formed by a convex mirror will be same.
1 Both assertion and reason are correct and reason is the correct explanation of assertion.  
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.  
3 Assertion is true but reason is false.  
4 Assertion is false but reason is true.  

Ans.

(3)

Convex mirrors are used for rear view on vehicles. We use only convex mirrors for rear view. Convex mirrors will always give erect and diminished image of the object. They provide a wider field for clear view. For this reason, the convex mirrors are fitted on both sides of the vehicles. Thus, the assertion is true but reason is false.
