Question

two blocks A and B of masses 8kg and today respectively on the horizontal frictionless surface as shown in the figure they are used by horizontally applied force of 50 Newton force exerted by b on a is ​

Answer 1

Answer:

3 Newton

Explanation:

Let N be the normal applied between the block and by Newton's third law the force applied by B on A will be equal to force applied by A on B , that is equal to N

Acceleration of both blocks will be equal and taking whole as system acceleration is » 15/10

Writing equation according to the FBD ( Free Body Diagram ) :

On block A

→ 15 - N = 8a { a = 15/10 }

→ 15 - N = 8 * 15/10

→ N = 3 Newton

Verification by writing equation on block B

→ N = 2a { a = 15/10 }

→ N = 2 * 15/10

N = 3 Newton
