Answer:
2.25 N upwards
Explanation:
Answer:
800 N/C to the right
Explanation:
The equation that relates force on a charge, electric field and charge is
[tex]F=qE[/tex]
where
F is the force acting on the charge
q is the charge
E is the electric field
In this problem, we have
[tex]E=15 N/C[/tex] is the electric field
[tex]q=-0.15 C[/tex] is the charge
Substituting into the formula, we find the force
[tex]F=(-0.15 C)(15 N/C)=-2.25 N[/tex]
Concerning the direction:
- The electric field and the force have same directions if the charge is positive
- The electric field and the force have opposite directions if the charge is negative
Here the charge is negative, so the electric field has opposite direction to the force: therefore, it must be upwards.
