With ex please Friday Homework Problem 5.8 B pt(s) J In a region of space the electric potential is where m 150 is a constant Calculate the electric field at the point (3m,o,o) in the region. Select One of the Following (a) E 508i (b) E 508i 450 R Friday Homework Problem 5.9 [3 pt(s) J The electric feld in a conductor is zero because (select the answer that fits BEST) Select One of the Following (a) the field lines cannot penetrate. (b) that's just a property of conductors. There is no further explanation. (c) a surface urge is induced, which sets up a feld that cancels the applied field. (d) the mobile electrons block the field. Friday Homework Problem 5.10 B pt(s) J A positive point charge of charge +Qis placed neutral conducting box as shown to the right. What is the electric flux through the spherical Gaussian surface drawn (dashed line)? conductor
Explanation / Answer
5.8) b)E = -150 N/C
explanation:
V(x) = gamma x
gamma = 150 N/C
E = V(x)/x
V(3,0,0) = (0 - 150*3) = - 450
E = -450/3 = 150
b)(c)
because: charge of a consuctior resides on the surface, free charge inside it is zero. since the charges on surface and induced inside the surface are of same magnitude so they cancels out.
