Final answer:
The electric field strength between two parallel conducting plates can be calculated using the formula: Electric Field Strength = Potential Difference / Distance.
Step-by-step explanation:
The electric field strength between two parallel conducting plates can be calculated using the formula:
Electric Field Strength = Potential Difference / Distance
In this case, the electric field strength is given as 2.50 × 10^4 N/C and the spacing between the plates is 0.900 mm. Converting the spacing to meters, we have 0.900 mm = 0.900 x 10^-3 m.
Therefore, the electric field strength between the plates is 2.50 × 10^4 N/C divided by 0.900 x 10^-3 m, which is equal to 2.78 x 10^7 N/C.
