Question

A block is lying on the table. What is the angle between the action of the table and the reaction of the book?

• A. $0^0$
• B. ${45}^0$
• C. ${90}^0$
• D. ${180}^0$

Answer 1

The correct option is D ${180}^0$

Action Force and Reaction Force are in opposite directions.
So,

the angle between them is ${180}^o$

Hence,

option $D$ is correct answer.
