Answer:
Please see below as the answer is self-explanatory.
Explanation:
- If the potential at B is lower than A, and the potential at C is lower than B, this means that there is an electric field, directed from A to C.
- If a positively-charged particle is released at rest at point B, it will be accelerated by the electric field (which is a force per unit charge, so it produces an acceleration) in the same direction than the field (because it is a positive charge) towards point C.
Answer:
<h3>0.69</h3>
Explanation:
Using the Newtons law of motion;

Fm is the moving force = 400N
Ff is the frictional force = μR
μ is the coefficient of kinetic friction
R is the reaction = mg
m is the mass
a is the acceleration
The equation becomes;

Hence the coefficient of kinetic friction between the box and floor is 0.69
