matlab The electric potential around a charged particle is given by , where ε=8.854x10-12V=14πrqC/Nm2 , q is the charge and r is the distance from the particle. The electric potential of 2 particles at a point P is given by , where q1 and q2 are the particles charges and r1 and r2V=14π(q1r1+q2r2)are distances from the particles to P. Two particles with charges q1=2x10-10 C and q2=3x10-10 C are located in the x-y plane at (0.25,0) and (-.25,0). Calculate and plot the electric potential due to the particles at points in the x-y plane located in the domain -0.3<=x<=0.3 and -0.3<=y<=0.3.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
