Answer:
False
Explanation:
The formula of force that exists between two charges is expressed as;
F = kq1q2/r²
If two charges separated by one meter exert a 9 N force on each other, the;
9 = kq1q2/1²
9 = kq1q2 ..... 1
If the charges are pushed to a 3 meter separation, then;
F = kq1q2/3²
F = kq1q2/9 .... 2
Divide both equations;
9/F = (kq1q2)/ kq1q2/9
9/F = kq1q2 * 9/ kq1q2
9/F = 9
F = 9/9
F = 1N
Hence if the charges are pushed to a 3 meter separation, then the force on EACH charge will be 1N. Hence the answer is False
The equivalent resistance is D)
Explanation:
The equivalent resistance of n resistors in parallel is given by the equation:
For three resistors such as in this problem, the equation becomes
where we have the following:
is the resistance of the 1st resistor
is the resistance of the 2nd resistor
is the resistance of the 3rd resistor
Substituting, we find the equivalent resistance:
