The equation of projectile is y = ax - bx2 . its horizontal range is?

Range,

Explanation:

The equation of trajectory is:

Where, is the angle of projectile, R is the horizontal range.

The equation of projectile is:

y = ax-bx²

On comparing:

Hence, the horizontal range is

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
