I think nobody can solve this question in MCQ, go to nov 2002 q.36. What the hell is that?
We Just find the PD dropped on each of X and Y and find the difference...
The answer is coming as 0.67V.
The PD will be.. Reading at Y - Reading at X.
since Y is after 2 Resistors... the resistance will be 4/3 V .. and at X there is only one resistor.. so Resistance is 2/3.
Y-X .. = 4/3 - 2/3 = 2/3 Answer.

Can you help with w11 p12 no. 15 ? please
Question what?i need 2003 nov solution? plz
May I? mg-kv=o because the velocity is constant. mg=kv. Rearrange the formula to find v, then use 1/2m(v^2) to find the K.E.
Can you help with w11 p12 no. 15 ? please
W=Fs
Fs=Change in Kinetic Energy..
Fs=4
When Both the F and s are multiplied by 2... we get..
Change In Kinetic Energy
=2F*2s
=4Fs
=4(4)
Change in KE = 16J..
Initial was 4J.. so 16+4 .. Answer is 20J.
mg is the weight, so the force downwards. kv is the air resistance, so the force upwards. The velocity is constant, so there's no resultant force. If you add the two forces, you must get 0. mg+-kv=o. +-=-.
15. WD=Fs. If Fs=2, then 2F2s=x. Cross multiply and you'll get 16. Add that to 4 to get 20.
Thanks to both of you ?
Why should we add 4 ?
