The line segment joining (5, 0) and (10"cos"theta,10"sin"theta) is divided internally in the ratio 2:3 at P. If theta varies, then the locus of P is

The line joning (5,0) and (10costheta,10sintheta) is divided internally in the ratio 2:3 at P. Then locus of P is

The line joining (5,0) to (10cos theta,10sin theta) is divided internally in the ratio 2:3 at P then the locus of P is

The line joining (5,0) to (10cos theta,10sin theta) is divided internally in the ratio 2:3 at P then the locus of P is

The line joining (5, 0) to (10 cos theta, 10 sin theta ) is divided internally in the ratio 2 : 3 at P. the locus of P is

The line joining (5, 0) to (10 cos theta, 10 sin theta ) is divided internally in the ratio 2 : 3 at P. the locus of P is

The line joining (5, 0) to (10 cos theta, 10 sin theta) is divided internally in the ratio 2 : 3 at P. If theta varies, then locus of P is (x - 3)^2 + y^2 = m^2 , then the value of m is :
