Question

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

Answer 1

this realtionship holds:
\[\Delta V = Ed\]

Answer 2

200*2.0 ?

Answer 3

:/

Answer 4

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

Answer 5

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

Answer 6

yes!

Answer 7

yay! thanks!!:D

Answer 8
