The magnitude of that other charge will be 9×10⁻⁵ C. The force on the charge is inverse of the distance.
<h3>What is Columb's law?</h3>The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The magnitude of that other charge is found as;
Hence, the magnitude of that other charge will be 9×10⁻⁵ C.

Answer:
Time taken to accelerate to 48 m/s = 8 seconds
Explanation:
Initially the object is moving south at =
So, initial velocity of the object =
Acceleration caused by the force = 4
Final velocity towards south =
Using equation of motions:
where
final velocity
initial velocity
acceleration
time
Plugging in values.
Subtracting both sides by 16
Dividing both side by 4.
∴
Time taken to accelerate to 48 m/s = 8 seconds
