A system contains five charges +1 C, +2 C, −3 C, +4 C and -5 C. The net charge on the system is +1 C -2 C 2 C -1 C
Answers
Given : A system contains five charges +1 C, +2C, -3 C, +4 C and -5 C.
To Find : The net charge on the system
a) +1 C
b) -2 C
c) 2C
d) -1C
Solution:
system contains five charges +1 C, +2C, -3 C, +4 C and -5 C.
net charge on the system will be summation of all charges
+ 1 C + 2C - 3C + 4C - 5C
+7C - 8C
= - 1C
The net charge on the system is - 1C

Explanation:
Charges calculations are simply like mathematics addition. Charges are generally positive and negative while their strength depends on the amplitude of charge. Unit of charge is coulomb with a symbol of C.
Now if we have five charges, net charge will be the sum of all.
= (+1) + (+2) + (-3) + (+4) +(-5)
= -1
Net charge on system will be -1 C
