If 2f(x^(2))+3f((1)/(x^(2)))=x^(2)-1x varepsilon R_(0) then f(x^(2)) is

If A={x in R:x^(2)+6x-7 0} then which of the following is/ or correct 1)A nn B={x varepsilon R:-2

Two charges,each equal to 2C can be placed so that the force between them equals to the weight of an object of mass 1kg .The distance between them is (take "g=10m/s^(2)" ) (10 pi varepsilon_(0))^(1/2), [1/(10 pi varepsilon_(0))^(1/2)], [1/10 pi varepsilon_(0)], [10 pi varepsilon_(0)]

If -3x+12<0 then x varepsilon

varepsilon_(0)E^(2) has the dimension of ( varepsilon_(0) = permittivity of free space, E = electric field)

Solve (|x|-1)/(|x|-2)>=0;x varepsilon R;x=+-2

The electric field at a point P which is at a distance l on the perpendicular bisector of a uniformly charged wire of length 1 , charge Q=(Q)/(2 pi varepsilon_(0)l^(2)sqrt(k)) where k = ?
