Ron and hermoine are fighting over the monster book of monsters and they are both pulling on the book with a force of 14 n (equally and in opposite directions). what will happen to the book in this situation? a) the book will slide towards ron b) the book will slide towards hermoine c) the book will fly up in the air d) the book will not move

The correct answer to the question is :  D) The book will not move.

EXPLANATION :

As per the question, Ron and Hermoine are applying same amount of force on the book.

Let the force applied by Ron is .

Let the force applied by Hermoine is

As per the question, the two forces are equal and opposite i.e anti parallel.

Hence, we may write two forces as .

Hence, the net force acting on the book is calculated as -

Hence, the net force on the book is zero. So, the book will not move.

Hence, the correct option of the question is option D.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

true tan speed = ang vel x radius
