Fig. represents vertical sections of four wings moving horizontally in air. In which case the force is upwards

What is the air moving horizontally called ?

The vertical sections of the wing of a fan are shown. Maximum upthrust is in

The direction of force on an upward moving ball is from

In the fig shown XX represents a vertical plane perpendicular to the plane of the fig. To the right of this plane there is a uniform horizontal magnetic field B directed into the plane of the fig. A uniform electric field E exists horizontally perpendicular to the magnetic field in entire space. A charge particle having charge q and mass m is projected vertically upward from point O. It crosses the plane XX after time T. Find the speed of projection of the particle if it was observed to move uniformly after time T. It is given that qE = mg.

In Fig. 2.6, BC represents a body moving

In case of projectile motion, which one of the following figures represent variation of horizontal component of velocity (u_x) with time t ? (assume that air resistance is negligible)

A box with weight 10N rests on a horizontal surface. A person pulls horizontally it with a force of 3N and it does not move. To start its motion, a second person pulls it vertically upward. If mu_(s)=0.5 and mu_(k)=0.3 , then find the smallest vertical force for which the box starts moving.
