## anonymous one year ago A voltmeter reads 200.0 V between parallel plates that are 2.0 cm apart. What is the strength of the electric field between the two plates? A. 1.0 × 10^1 N/C B. 1.0 × 10^2 N/C C. 1.0 × 10^3 N/C D. 1.0 × 10^4 N/C

this realtionship holds: $\Delta V = Ed$

200*2.0 ?

3. anonymous

:/

4. Michele_Laino

no, we have: $E = \frac{{\Delta V}}{d} = \frac{{200}}{{2 \times {{10}^{ - 2}}}}$

ohh oops!! so we get 10,000 ? so our solution is choice D?

6. Michele_Laino

yes!

7. anonymous

yay! thanks!!:D
