Question ( part 1 of 4 )I' wo charges are located in the ( 2 , 7 ) plane*as shown . The fields produced by these*charges are observed at a point p with co-ordinates ( 0 . 0 ) .A P &1. 6 m1 . 6 m8.709. 20- 2.5 m-- 2 m-OFind the I- component of the electricfield at p.The Coulomb constant is8. 98755 x 10' N . M 2 / 02.Answer in units of N / C .Question ( part 2 of 4 )Find the electric potential at p with coordi -nates ( 0 . 0 ) . Let V _ O at infinity .Answer in units of V .`
