Question

please give a correct answer​

Answer 1

Answer:

If x and Y is a two pont

Explanation:

i =?

n=20000000

e is constant =

$1.6 \times {10}^{ - 19}$

t =1 micro sec so no changes.

$i \ = \frac{ne}{t}$

$i \ = \frac{20000000 \times 1.6 \times {10}^{ - 19} }{1}$

then

$i \ = \frac{2 \times 1.6 \times {10}^{ - 12} }{1}$

$i = \frac{2 \times 16 \times {10}^{ - 12} }{10}$

$i = \frac{32 \times {10}^{ - 12} }{10}$

$i = \frac{3.2 \times {10}^{ - 12} }{1}$

i =3.2×10^(-12). then i = also a negative direction like electron..
