If the force between two charged objects when you triple the magnitude of both charges. The Force will become 9 times the initial force.
<h3>What is coulombs law?</h3>
According to coulombs law force between two charges is given by
Here, R is the distance between both the charges Q and q.
Let the force on the charges be F1
The distance of separation = r
The magnitudes of the charges q1 and q2
K = Coulumb's constant
Let the force on the charges be F
The distance of separation = r
The magnitudes of the charges 3q1 and 3q2
K = Coulumb's constant
So,

The number of terms, 'n' is 8
<h3 /><h3>How to determine the number of terms</h3>
Let's determine the common ratio;
common ratio, r = 3/1 = 3
The formula for sum of geometric series with 'r' greater than 1 is given as; Sn = a( r^n - 1) / (r - 1)
n is unknown
Sn = 3280
Substitute the value
3280 = 1 ( 3^n - 1) / 3- 1
3280 = 3^n -1 /2
Cross multiply
3280 × 2 = 3^n - 1
6560 + 1 = 3^n
6561 = 3^n
This could be represented as;
3^8 = 3^n
like coefficient cancels out
n = 8
Thus, the number of terms, 'n' is 8
