Q1
A student compares two situations with the same book on the same table.
Situation 1: The book is resting. Forces on the book: weight $10,\text{N}$ downward and normal force $10,\text{N}$ upward.
Situation 2: The student pushes the book to the right with $12,\text{N}$ while friction pulls left with $7,\text{N}$ (the $10,\text{N}$ weight and $10,\text{N}$ normal force still act).
Which statement correctly compares the net force and motion in the two situations?
