The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

2L A thin rod of length 24 = 5.3 cm is centered on the x axis. The rod carries a nonuniform linear charge density 1 = ax, where a = 0.118 uC/m . Determine the electric potential V at a point along the x axis a distance 8.5 cm from the center of the rod. 00 V = V abc sin(x Ox10 Submit Reset Reset All .Begin as usual by writing an expression for the infinitesimal potential dV produced by the charge dq on an infinitesimal segment dx of the rod. Note that dq will depend on x, because the charge is nonuniformly distributed. .It may help to denote the distance to the (fixed) observation point by xo, to distinguish this distance (8.5 cm) from the variable distance x from the center of the rod to one the charged segments on it
