Answer:
The magnitude of electric field is
in downward.
Explanation:
Given that,
Force 
Charge q= -2.00 μC
We know that,
Charge is negative, then the electric field in the opposite direction of the exerted force.
We need to calculate the magnitude of electric field
Using formula of electric force




Negative sign shows the opposite direction of electric force.
Hence, The magnitude of electric field is
in downward.
Answer:
weight
Explanation:
weight is the pull of gravity so its a force !!
Answer:
Removing some of the books reduced the mass of the box, and less force was needed to push it across the floor.
