Question 1.

potential energy=mgh; where h=(90-x)

Kienatic energy= .5mv^2

According to the condition

3*m*g*(60-x)= .5mv^2

x=90-(V^2/58.86).........(Ans)

Question 2.

Q=(KA/d)(T1-T2)

1/K=1/K1+1/K2+1/K3

1/K=1/0.125+1/1.5+1/1=8+.667+1=9.667

Q=(9.667*140/.295)*(22-(-10))=8474576271186

Question 3.

As network is weatston bridge so 50 ohm resistance is inactive.

Reqv= (15+15)||(30+30)

Reqv = 20 ohm.......(Ans)
