Trignometry | Ratios | Q/A | Part2

Highest q/m ratio is for:

If x+y+z=xyz , prove by trignometry that: (2x)/(1-x^(2))+(2y)/(1-y^(2))+(2z)/(1-z^(2))=(2x)/(1-x^(2)).(2y)/(1-y^(2)).(2z)/(1-z^(2))

The equilibrium constant K_(p_(2)) and K_(p_(2)) for the reactions A hArr 2B and P hArr Q+R , respectively, are in the ratio of 2:3 . If the degree of dissociation of A and P are equal, the ratio of the total pressure at equilibrium is,

R.Q. is ratio of

A stationary shell of mass M explodes in to two parts and their masses are in the ratio 2:3, then the ratio of their deBroglie wavelengths is

If the roots of the quadratic equation ax^2 + cx + c = 0 are in the ratio p :q show that sqrt(p/q)+sqrt(q/p)+sqrt(c/a)= 0 , where a, c are real numbers, such that a gt 0

If point P(3,2) divides the line segment AB internally in the ratio of 3:2 and point Q(-2,3) divides AB externally in the ratio 4:3 then find the coordinates of points A and B.

Two charge Q_1 and Q_2 are placed in xy plane at a distance x_1 and x_2 from origin a shown in figure. if electric field at O is same for both charge then find ratio Q_1 and Q_2 .

Let p and q be the position vectors of P and Q respectively with respect to O and |p| = p, |q| = q . The points R and S divide PQ internally and externally in the ratio 2 : 3 respectively. If vec( OR) and vec(OS) are perpendicular, then (A) 9p^2=4q^2 (B) 4p^2=9q^2 (C) 9p=4q (D) 4p=9q

A charge Q is divided into two parts. Charge on each part is q. Also, Q//q=2 . What is the Columbic force between two charges q and q when both parts are placed certain distance apart?
