Find the circum-centre of the triangle whose vertices are A (-3 , -1) , B( 1,2) and C( 0 , -4) .

Ten positively charged particles are kept fixed on the x-axis at points x=10cm, 20cm, 30cm, …, 100cm. The first particle has a charge 1.0xx 10^(-8)C , the second 8xx10^(-8) C, the third 27xx10(-8) C and so on. The tenth particle has a charge 1000xx10^(-8)C. find the magnitude of the electric force acting on a 1 C charge placed at the origin.

In Fig., particles 1 and 2 of charge q_(1) = q_(2) = +4e are on a y axis at distance d = 1.70 m from the origin. Particle 3 of charge q_(3) = +8e is moved gradually along the x axis from x = 0 to x = +5.0 m. At what values of x will the magnitude of the electrostatic force on the third particle from the other two particles be (a) minimum and (b) maximum ? What are the (c ) minimum and (d) maximum magnitudes ?
