On a circle with centre (2, 1) and radius 3, a variable point 'A' is taken, such that perpendiculars from 'A' on a diameter of circle are divided by a point B in a fixed ratio 1 : 3. Then (B) locus of point B is an ellipse concentric with circle with eccentricity √7 /4 (D) If locus of B is a curves 'S' then the locus of perpendicular drawn from foci of S upon any tangent to it, is the given circle itself?

Pragraph 1A frame of reference that is accelerated with respect to an inertial frame of reference is called a non-inertial frame of reference. A coordinate system fixed on a circular disc rotating about a fixed axis with a constant angular velocity ω is an example of a non-inertial frame of reference. The relationship between the forceexperienced by a particle of mass m moving on the rotating disc and the force experienced by the particle in an inertial frame of reference iswhere is the velocity of the particle in the rotating frame of reference and is the position vector of theparticle with respect to the centre of the disc. Now consider a smooth slot along a diameter of a disc of radius R rotating counter-clockwise with a constant angular speed ω about its vertical axis through its center. We assign a coordinate system with the origin at the center of the disc, the x-axis along the slot, the y-axis perpendicular to the slot and the z-axis along the rotation axis. A small block of mass m is gently placed in the slot atand is constrained to move only along the slot.Q.The net reaction of the disc on the block is
