Maximum volume of cornflakes that the box can hold is 375 in³
Step-by-step explanation:
Step 1: Given the rectangular box is right angled, then it is a cuboid. Volume of the cuboid = length × width × height (Here, length and width are the same since it has a square base)
F = kq2 / r2 q = ne F = k(ne)2 / r2 n = âš(r2F / ke2) = (r/e) âš(F/k) k = 9 x 109 Nm2/C2 e = 1.6 x 10-19 C n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
