Question

Pick the correct option for the following statements:
Statement 1: We apply oil on door hinges to reduce friction.
Statement 2: Friction can be reduced by streamlining the shape of the object.

• A. Statement 1 is true, statement 2 is false
• B. Statement 1 is false, statement 2 is true
• C. Both statements are true
• D. Both statements are false

Answer 1

The correct option is C Both statements are true

Lubrication reduces the friction between the moving parts of the body. Oil acts as a lubricant and reduces friction if we apply it on the door hinges.
Frictional force also depends on the shape of the object. Friction can be reduced by streamlining the shape of the object.
Hence, both statements are correct.
