1. Two electrical sub-networks N, and N, are
connected through three resistors as shown in
Fig. 2.112. The voltages across the 5-22
resistor and 1-2 resistor are given to be 10 V
and 5 V respectively. Then the voltage across
the 15-12 resistor is
(a) -105 V
(b) 105 V
(c) -15 V
(d) 15 V

Answer 1

when the is x−y

⟾ Dist=100km

⟾ =5 hours

⟾ Dist =S×T

⟾ 100=(x−y)5

⟾ x−y=20⟶(I)

when THE is x+y

⟾ Dist=100km

⟾ t=1 hours

⟾ Dist=ST

⟾ 100=(x+y)1

⟾ x+y=100⟶(II)

⟾ x−y=20

⟾ x+y=100

​⟾ 2x=120

⟾ x=60km/h
