German physicist werner heisenberg related the uncertainty of an object's position (δx) to the uncertainty in its velocity (δ δx≥ℎδ where ℎ is planck's constant and m is the mass of the object. the mass of an electron is 9.11×10−31 kg. what is the uncertainty in the position of an electron moving at 4.00×106 m/s with an uncertainty of δ=0.01×106 m/s?

Explanation:

As we know by the principle of uncertainty that the product of uncertainty in position and uncertainty in momentum is given as

so here we know that

so we have

the force required to move the cart is divided by three or 33.33 n.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
