Charge 9 × 10−18 C is on the y axis a distance 5 m from the origin and charge 9 × 10−18 C is on the x axis a distance d from the origin. What is the value of d for which the x component of the force on 9 × 10−18 C is the greatest? The Coulomb constant is 8.98755 × 109 N · m2 /C 2 .

d = 3.53 m

Explanation:

The Coulomb Force is given as

The x-component of the force is equal to

This is basically a function of (d). So, the maximum value of this function is the point where its derivative with respect to d is equal to zero.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
