What is the net electric force on the charge located at the lower right-hand corner of the triangle shown here?.

250✖️100 to get you answer

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

Iwas thinking the wavelength is one half its original value

Answer is trees if this doesnt try using google
