1.An object is moving in the xyxyxy plane with position as a function of time given by r⃗=x(t)i^+y(t)j^\vec{r} = x(t)\hat{i} + y(t)\hat{j}r=x(t)i^+y(t)j^. The object is definitely moving towards the origin OOO whena.vx>0v_x > 0vx>0, vy<0v_y < 0vy<0b.vx<0v_x < 0vx<0, vy<0v_y < 0vy<0c.xvx+yvy<0x v_x + y v_y < 0xvx+yvy<0d.xvx+yvy>0x v_x + y v_y > 0xvx+yvy>0Login to continueOnly logged in users canattempt or see the solution.
