Final answer:
The electric field between two parallel metal plates can be calculated using the formula E = V/d, where E is the electric field, V is the potential difference between the plates, and d is the distance between the plates. In this case, the potential difference is given as 75 V and the distance between the plates is given as 15 cm (or 0.15 m). Therefore, the electric field between the two plates is 500 V/m.
Step-by-step explanation:
The electric field between two parallel metal plates can be calculated using the formula E = V/d, where E is the electric field, V is the potential difference between the plates, and d is the distance between the plates. In this case, the potential difference is given as 75 V and the distance between the plates is given as 15 cm (or 0.15 m).
Substituting the given values into the formula, we get E = 75 V / 0.15 m = 500 V/m.
Therefore, the electric field between the two plates is 500 V/m.
