The Coulomb unit is a Derived Standard, while the Ampere unit is a Fundamental Standard. Even so, electric charge is fundamental, and electric current is just the flow-rate of charge.

The first practical realisation of the metric system came in 1799, during the French Revolution, when the existing system of measures, which had become impractical for trade, was replaced by a decimal system based on the kilogram and the metre.

Dhruv Sarkar 6 years, 6 months ago

Let the frequency be v.Now, v=kL^aF^b(m/l)^c, where k is the constant of proportionality.By taking the dimensions of the LHS and RHS we get, [M^0L^0T^-1]=[L^a][M^bL^bT^-2b][M^cL^-c] [M^0L^0T^-1]=[M^b+cL^a+b-cT^-2b] By equating the powers we get, b=1/2; c=-1/2 and a=-1 Hence by putting the values we get, v=(k/L)×(√F/m)

Posted by Utkarsh Nikam 6 years, 6 months ago

Gaurav Seth 6 years, 6 months ago

Question:

The vector sum of the forces of 10N and 6N can be
(a) 2N
(b) 8N
(c) 18N
(d) 20N

Maximum resultant of vectors = 10 + 6 = 16 N
Minimum resultant of vectors = 10 - 6 = 4 N

Force should lie in between maximum and minimum resultant of vectors.

The force must lie between the range of maximum and minimum resultant of these vectors .

In option (a) , 2N ‹ 4N
In option (b), 4N ‹8N ‹16N , it lies between the range So, this is correct answer.
In option (c) 18N › 16N
In option (d) 20N›16N

Hence, option (b) is correct.
