Ten positively charged particles are kept fixed on the x - axis at points x=10cm,20cm,30cm,⋯,100cm.The first particle has a charge 1.0×10−8C, the second 8×10−8C, the third 27×10−8C, and so on. The tenth particle has a charge 1000×10−8C. Find the magnitude of the electric force acting on a 1 C charge placed at the origin. |
