If e1 = 13.0 v and e2 = 5.0 v , calculate the current i2 flowing in emf source e2.

The solution would be like this for this specific problem:

KCL at Junction a. 
+ I1 + I2 + I3 = 0 (1) 

KVL
+ 13 V - 0.2 R I1 - 0.025 R I1 - 5 V + 0.02 R I2 = 0 (2) 
8 + 0.02 I2 = 0.225 I1 
I1 = 35.6 + 0.0889 I2 (2A) 

KVL (bottom loop - CCW direction) 
- 0.02 R I2 + 5 V + 0.5 R I3 = 0 (3) 
0.5 I3 = -5 + 0.02 I2 
I3 = -10 + 0.04 I2 (3A) 

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

answer: i pick a
