Problem 28E

Approximating changes Approximate the change in the magnitude of the electrostatic force between two charges when the distance between them increases from ?r? = 20 m to r ? ? = 21 m (?F?(?r?) = 0.01/r2).

Step-by-Step Solution:
Step 1 of 3

Solution 28E STEP 1 According to the approximation formula we can write f(x + x) f(x) = f(x).x f = f x).x, Where f is the function,x is the variable and x is the change in x. STEP 2 Therefore according to this question, we have to approximate the change in the magnitude of the electrostatic force between 2 charges when the distance between them increases from r=20m...
