Answer: 1.274 N minimum force required to slide the book across the surface
Explanation:
Mass of the book = m = 0.2 kg
Normal force acting on the book,N = mg
Coefficient of friction = = 0.65
Minimum force required to slide the book across the surface= F
1.274 N minimum force required to slide the book across the surface
