Answer:
A
Explanation:
The electric field = 1000N/C
Using the formula
F = q/4πeD^2 where F is the force experience by a charge body brought from infinity to D and e is the field constant in C/N.m^2 and D is the distance from the uniform field
1000 = q/4πeD^2
Make q subject of the formula
1000*(4πeD^2) = q
If the force changes to 2000 then equation changes to:
2000 = q /4πeD1^2 where D1 is the new distance
Substitute q in equation 2
2000 = 1000*(4πeD^2) / 4πeD1^2
Cancel 4πe
2000 = 1000 * D^2 / D1^2
Cross multiply and make D1^2 subject of the formula
D1^2 = 1000D^2/ 2000
D1^2 = D^2/2
Take square root of both side
D1 = √(D^2/2) = D / √2
Acceleration is velocity over time. in order to find velocity, you divide distance over time

Triton was discovered by British astronomer William Lassell on October 10, 1846, just 17 days after the discovery of Neptune.
Triton is named after the Greek sea god Triton (Τρίτων), the son of Poseidon (the Greek god corresponding to the Roman Neptune).
Just multiply the "1.0 m/s" by ' 1 ' a few times. (Remember that a fraction with the same quantity on top and bottom is equal to ' 1 ' .)
(1.0 m/sec) · (1 km/1000 m) · (60 sec/min) · (60 min/hr) =
(1.0 · 60 · 60 / 1,000) (m · km · sec · min / sec · m · min · hr) =
(3,600 / 1,000) (km / hr) =
3.6 km/hr .
