Question

4.0C -60c 34. Charges ore and Pile, are placed at two comen ofanequilateral triangle with sides ofuo what is the electric field magnitude created by these two charge?n- m. At the third corner, the a. 45 x 10 NC b. 3.1 x 10 NC c. 1.6x 10 NIC d. 4.8 x 10 N/C X-Comp. Y-Comp 6 Figure 19-20 78) A uniform electric field with a magnitude of 8 10 N/C is applied to a cube of edge lengths Q.1 m as shos A) 0.8 x 10 Nm/C C) 80 x 10 Nm/C Figure 19-20. If the direction of the E-field is along the +7-axis, what is the eloctric fhux passing through the shade face of the cube? D) 800 x 10 Nnc

Explanation / Answer

51.

P= Vi

500= V* 4

= 125 V

--------

6.

Emf of the battery is given by

E= V+ ir

E= i(R+r)

12/0.482- 24 = r

r= 0.9 ohm.

---------

31.

Net resiatares of the circuit

R= 6+ 7*(4+10)/(7+4+10)

= 10.7 ohm

--------

21.

Net resistance of circuit.

R= 2+ [ 1/4+1/6+1/10]^-1

R= 3.935 ohm

Net current through circuit, i= V/R= 12/3.935= 3.05 A

Voltage across 10 ohm resistor

V10= V- iR= 12- 3.05* 2= 5.9 V

I10* 10= 5.9

I10= 0.59 A
