Answer:

Step-by-step explanation:
From the question we are told that
Charge 
Force 
Generally the equation for electric field strength is mathematically given as


Therefore

Answer:
38
Step-by-step explanation:
We are to solve for the expression;
2 + 3² × (5 - 1)
We should aply BODMAS here!
So starting with the brackets;
2 + 3² × 4
Then solving the multiplication part;
3² × 4 = 9 × 4 = 36
Finally adding the integers;
2 + 36 = 38
In order to solve 5 + y = 7 you have to find the value of (y). In this case you could reverse do problem and do 7 - 5 to get the value of y. 7 - 5 = 2, which means y is equal to 2.
0.188 because the 5 in 0.1875 rounds up
