A point in the electric field of two different charged particles is 300 cm from the negatively charged particle, and 600 cm from the positively charged particle. The charge of the positive charge is 6 nC, the charge of the negative charge is -3 nC. What is the strength of the electric field at the point of measurement? * 1 point
-1.5 N/C
-5.2425 N/C
-1.49 X 10^-4 N/C
1.5 N/C

The position of a dragonfly that is flying parallel to the ground is given as a function of time by r⃗ =[2.90m+(0.0900m/s2)t2]i^− (0.0150m/s3)t3j^. a: at what value of t does the velocity vector of the insect make an angle of 34.0 degree clockwise from the x-axis? b: at the time calculated in part (a), what is the magnitude of the acceleration vector of the insect? c : at the time calculated in part (a), what is the direction of the acceleration vector of the insect?

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Which articulations allow for greatest range of motion?
