Calculate the magnitude and direction of a vector whose x and y components are given to be 30 and 40 units respectively.

Magnitude = 50 units

Direction = 53.13°

Explanation:

The formula to find out the magnitude of a resultant vector with the help of its x and y components is given as follows:

where,

x = 30 units

y = 40 units

Therefore,

Magnitude = 50 units

Now, the direction of the resultant vector will be given by the following formula:

Direction = 53.13°

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.)
