Explanation:
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR)
A 1 or 2 electrons because it is the brainless answer
let the ron and hermoine apply force along the horizontal direction . let ron pulls in left direction. and hermoine pulls towards right
lets assume that the left direction is taken as negative and right direction as positive.
F = force applied by ron towards left
F' = force applied by hermoine towards right
a = acceleration of the book
m = mass of book
force equation for the book is given as
- F + F' = ma
Given that : F = F'
hence
- F' + F' = ma
0 = ma
a = 0 m/s²
since the book was initially at rest and the acceleration comes out to be zero, hence the book will not move.
so correct choice is
D) The book will not move
both it velocity and acceleration is zero.
