Find the v first by using 3.14x0.22x2.16 div. 41g
Answer:
2.7 m/s²
Explanation:
Average acceleration is change in velocity over change in time. Assuming the acceleration is constant, we can say it is equal to the average:
a = Δv / Δt
a = (6.0 m/s - 0 m/s) / 2.2 s
a ≈ 2.7 m/s²
Answer:
The distance between the charges is 9.5 cm
(c) is correct option
Explanation:
Given that,
Charge 
Force F = 1 N
We need to calculate the distance between the charges
Using Coulomb's formula

Where, q = charge
r = distance
F = force
Put the value into the formula




Hence, The distance between the charges is 9.5 cm
