The electric field strength depends only on the x, y, and z coordinates according to the law E = (a(xhati+yhatj+zhatk))/(x^2+y^2+z^2)^3//2, wherea = 280 Nm^2C^(-1) is a constant. If the potential difference between (3,2,6) and (0,3,4) is x^2. What is the value of x. |

Answer» Solution :`vecE=(avecr)/(r^(2))` `V=(-a)/(r)` `triangleV=(a)/(r_(2))-(a)/(r_(1))=(a)/(5)-(a)/(7)=(2a)/(35)=2XX(280)/(35)=16V=4^(2)` |
