Answer to Question #49049 in Mechanics | Relativity for aslan
The 20 kg suitcase A is released from rest at point C of height 3 m from floor ED. The suitcase slides down a friction-less ramp between C and E and continues sliding on the floor until stopping at a certain distance from E.
The coefficient of friction between the floor ED and suitcase A is µ(ED) = 0.4.
Consider g = 9.8 m/s2
Calculate the distance in m from point E reached by suitcase A as it stops
We can change the electromagnetic field bychanging the distance from point at 100 meters away (we change electric field of our charge) or by moving the charge with acceleration (we induct magnetic field). If we decrease the distance an electron ona metal ball would be located on the nearest side of the ball. If electron doesn’t move the magnetic field doesn’t act on it.
