General Studies Preliminary Paper May 15, 2005
First of all, thanks to SUDHAKAR TRIPATHI for attempting to give the answer to a pending question. He has suggested the following answer: RESITANCE OF HUMAN BODY IS ABOUT 1000000 OHM IN DRY STATE.
However, the answer is as follows:
121. What is the order of magnitude of electric resistance of human body (dry)?
(a) 102 ohm
(b) 104 ohm
(c) 106 ohm
(d)108 ohm
Ans: Pending (Is it c; 10 raise to power 6 ohm) (Answer As Given earlier)
Final Answer: It is b; 10x10x10x10 ohm
Authentication/Validation/Verification/Argument/Elaboration
A dry body has a resistance nearly 10 k ohm. In other words, it is 10 raised to power 4 ohms.
Further 1 ohm = 1 volt/1 ampere = 1V/1A
This question relates to Current Electricity Chapter of Physics of 10+2, C.B.S.E syllabus and the issue appears in a exercise of NCERT book question no 3.42 page 104 edition November 2003, Chapter 3 titled "Current Electricity". However, the answers can be had from other books which is referred below.
In addition to that, it may also interest the aspirants.
International Ohm ( S.I unit of resistance)
It is defined as the resistance of 106.3 cm long mercury column of 1 square mm cross-section area and mass 14.4521 gram at 0º C.
A current of 0.01 A, that is 1/100 A is sufficient to send a shock in the body. A voltage of about 100 V is dangerous to health and 220 V may prove extremely fatal.
It further explained in the Chapter Current Electricity Unit 2 of Pardeep’s Fundamental Physics by Gomber and Gogia.
Answer provided by Prof. Parveen Sharma, Head of the Department of Physics, Arya College, Ludhiana.

Q76
ReplyDeleteBut you can not say that CO2 concentration is not there. It is also having high content of sulphur compounds which is also fatal for human life.
You can not say that R is not the reason of A therefore is A.
Just think once again, You will have the answer. Why do you refuse to deny truth to R.
Dear Tripathi,
ReplyDeleteQ 108
It seems that in 4 attempt it is possible to get all 10 sides of T upside.
The sequence can be as follows:
10H at Start
First Attempt
6 H 4T
Second Attempt
8H 2T
here 3T change over to 3H making 6H + 3T= 9H and leaving 1T
1H changes to 1T giving 2T and leaving 8H
Third Attempt
4H 6T
here 4H changes to 4T
Fourth attempt
10T
My sequence is different from your sequence. But it shows that minimum 4 attempts can be used to get 10T
What do you say?
I regret the delay as one of my article was pending for long and I am trying to complete that. Secondly whenever I come this blog, its settings are changed. It takes my second.
BTW why do you not activate yours lovegs.blogspot with title GSPoint.
