Find the equation of locus of P ,if the line segment joining (2,3) and (-1,5) subtends a right angle at P.

The line join of the points (2,3) and (-1,5) subtends a right angle at P. If the locus of P is a circle then its radius is

Find the locus of the mid point of the circle x^2+y^2=a^2 which subtend a right angle at the point (p,q)

The equation whose roots are (p-q)/(p+q) and -(p+q)/(p-q) will be

Let p and q be the length of two chords of a circle which subtend angles 36^@ and 60^@ respectively at the centre of the circle . Then , the angle (in radian) subtended by the chord of length p + q at the centre of the circle is (use pi=3.1 )

The resultant of two forces P and Q makes an angle of 30^(@) with P. What is the angle between P and Q, if the magnitude of the resultant is equal to Q sqrt(3) ?
