Statement-1 : For a charged particle moving from point P to point Q, the net work done by an electrostatic field on the particle is independent of the path connecting point P to point Q.
Statement-2 : The net work done by a conservative force on an object moving along a closed loop is zero
The ellipse x2+4y2=4is inscribed in a rectangle aligned with the coordinate axes, which in turn is inscribed in another ellipse that passes through the point (4, 0). Then the equation of the ellipse is
A focus of an ellipse is at the origin. The directrix is the line x=4and the eccentricity is 1/2. Then the length of the semimajor axis is
