Answer:
Explanation:
The charge of a single electron is:
If a droplet contains N electrons, then its charge would be:
In this case, the droplet has
N = 6
electrons, so its total charge is
<u>72 m</u> is the horizontal distance the travels.
Option: C
<u>Explanation</u>:
The units to express the horizontal and vertical distances are meters (m). The "horizontal" and "vertical" velocities are expressed in "meters per second" (m/s).
Horizontal distance = (initial horizontal velocity)(time)
We can now get the range x from the horizontal component of velocity
equation (1)
x = horizontal distance (m)
t = time (s)
We know that, V = 37 m/s, θ = 12 degree and t = 2 seconds.
To find,
x = 72.076 m ~ 72 m
x = 72 m
The horizontal distance is <u>72 m.</u>
