Work is equal to the force supplied multiplied by the distance moved, so it is 1200J.
No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.
when dipole moment,torque and electric field all the three are perpendicular to each other.
The force associated with Torque T is always perpendicular to the torque motion, T=FxR.
Normal Force
That's the torque due to the force.
Work is equal to the force supplied multiplied by the distance moved, so it is 1200J.
That is difficult to answer in that a horizontal force may be perpendicular to the body. So, the question does not differentiate between "can a vertical force cancel a horizontal force?" and "can a horizontal force cancel a horizontal force?" The best answer is, yes: two opposite and equal horizontal forces, both perpendicular to a body, will cancel each other.
No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.
Lift is the force that acts upwards, perpendicular to the chord of the wing. Thrust is the force acting perpendicular to the propeller disc.
If that force is not perpendicular to the surface, then there is a component of the force that's parallel to the surface. That component would move fluid around, until there were no longer any force parallel to the surface ... and the whole force would again be perpendicular to the surface.

A normal force is a force perpendicular to something - for example, to a surface. This force can be supplied by just about anything; in many cases by gravity.A normal force is a force perpendicular to something - for example, to a surface.

Perpendicular Force is the forces that acts at right angle to the object.

A rhombus has 4 equal sides and the diagonals are always perpendicular
It has 4 perpendicular lines, or 4 equal sides. However, not all lines are perfectly equal!
