Please solve these question in details and fully explaination.

1. In Figure (a) , particles I and of have charge 51. 0 C each and are held at seperation distance d= 180 m . a) What is the magnitude of the electrostatic force on particle i due to particle 2 ? 1b) In figure 6 ) , particle 3 of charge 51.0 MC is positioned so as to complete an equilateral triangle . . What is the magnitude of the net electrostatic force on particle I due to particles & and 3? 1 .- d 2 .. (a) (b) 2 . The Figure shows an arrangement of 4 charged particles , with angle D= 30.0 and distance d= 200 cm. Particle 2 has charge 9, = + 8.00 x 10 C; particle 3 and 4 have charges 93 = 94 = - 1.60 x 10'C What is the distance D between the origin and particle a if the net electrostatic force on particle I due to the other particles is zero . Assume that the charge of particle 1 is positive . - Please solve by first create the free -body diagram for particle 1
