Object A has a charge q on it, object B has a charge q on it, and Object C has a charge 2q on it. These charges are arranged, one each, at the vertices of an equilateral triangle. Which charge has the greatest magnitude electric force on it?a. Ab. Bc. Cd. All have equal magnitude forces on them.

Option d.

Explanation:

The force between charges can be expressed as:

F = k*q1*q2/r^2

where k is a constant, q1 and q2 are the charges and r is the distance between them.

We hare in a equilateral triangle, so al the distances are equal.

and the charges are:

qa = q

qb = q

qc = 2q

Now, for example, the force that experiments charge A is (in the y axis)

F = (k*qa*qb/r^2 + k*qa*qc/r^2)*cos(30°) = cos(30°)*(q + 2q)*k*q/r^2 = cos(30°)*3*k*q^2/r^2

for charge B, the force is again, in the y axis.

F = (k*qb*qa/r^2 + k*qb*qc/r^2)*cos(30°) = cos(30°)*(q + 2q)*k*q/r^2 = cos(30°)*3*k*q^2/r^2

for particle C, we have:

F = (k*qc*qa/r^2 + k*qc*qb/r^2)*cos(30°) = cos(30°)*(q + q)*k*2q/r^2 = cos(30°)*4*k*q^2/r^2

Wher the cosine of 30° comes because we have a equilatiral triangle, where all the internal angles are 60°, so if we draw a line that cuts the angle by half (our y-axis) the angles to each side are 30°.

We can do a similar process for the forces in the x-axis, and we will reach the same conclusion:

Now, this means that the force that experiences the charge C is the biggest force, so the correct option is c.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
