Answer:
Using the relation V^2 = U^2 + 2× a× S
V^2 = 50^2 + (2× 5 × 240 )
V^ 2 = 2500 + 2400
V^ 2 = 4900
V= (4900)^0.5 = 70 m/s
hence, velocity at a distance of 240 m will be 70m/s.
Now using the relation,
V= U + a× t
70 = 50 + 5 × t
20 = 5 × t
t = 20/5 = 4m/s
hence , time required to travel a distance of 240m will be 4s.

<h2>
Answer</h2>
To increase force decreases the distance between the charged particles.
<h2>
Explanation</h2>
According to coulomb's law
The force is directly proportional to the potential of two charges and inversely proportional to the distance between the charges. So if we want to increase the force 9 times, we have to reduce the distance 3 times because, one-time reduction in distance will have twice effects on the charges, as distance contain square on it.
