Hi everyone,
I present a situation here: Say there are two points A and B in space separated by a distance d. I create two charged particles (of any charge) at points A and B at time t=0. After how long will they experience force due to one another?
My answer: We know that electric fields travel at c (the speed of light= 3 x 108 m/s). So, the field from the charge at A will spread out in a spherical way at time t=0. Similarly, the field from B will spread out spherically at the same time t=0. These two field will meet each other at the midpoint on the line joining A and B at a time=d/(2c). We know that interaction of fields leads to force. Field is the cause and force is the effect. Hence, according to me, the answer is t=d/(2c).
Am I correct? If not, where am I going wrong?
