1.318m

Explanation:

The set up is a right angled triangle

Horizontal distance is the distance covered by the hurdler = 0.535m =adjacent

Angle of elevation = 67.9°

Height of the hurdler = opposite

Using the SOH CAH TOA identity

Using the TOA identity

Tan67.9° = opp/adj

Tan67.9 = opp/0.535

Opp = 0.535tan67.9°

Opp = 1.318m

Hence the required height is 1.318m

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.)

where's the following? you gotta add it to know what the choices are
