A plane mirror is placed at origin parallel of y-axis, facing the positive x-axis. An object starts from (2m, 0, 0) with a velocity of `(2hat(i)+2hat(j))m//s`. The relative velocity of image with respect to object is along

A plane mirror is placed along the x-axis facing negative y-axis. The mirror is fixed, A point object is moving with 3hati+4hatj in front of the plane mirror. The relative velocity of image with respect to its object is

A plane mirror is placed along the x-axis facing negative y-axis. The mirror is fixed, A point object is moving with 3hati+4hatj in front of the plane mirror. The relative velocity of image with respect to its object is

A plane mirror is placed along positive x-axis facing towards positive y-axis. If the equation of a linear object is x=y, the equation of its image is

A plane mirror is placed along positive x-axis facing towards positive y-axis. If the equation of a linear object is x=y, the equation of its image is

A point object is placed (0,0) and a plane mirror 'M' is placed, inclined 30^(@) with the x axis. (a) Find the position of image. (b) If the object starts moving with velocity 1 hat(i) m//s and the mirror is fixed find th e velocity of image.

Velocity of a swimmer with respect to a river is (hat i+4hat j)m/s and velocity of the river flow is (2hat j)m/s then velocity of swimmer with respect to ground is (in m/s)
