Hello,and please help me with the following questions:

17.An electron moves horizontally with a speed of 1.6x10^6 m/s between two horizontal parallel plates.The plates have a length of 12.5cm,and a separation that allows a charged particle to escape even after being deflected,as shown in the following figure.The magnitude of the electric field within the plates is 150N/C.Calculate the final velocity of an electron as it leaves the plates,keeping two significant figures.

18.A point charge q1 with charge 2.0x10^-6 C is initially at rest at a distance of 0.25m from a second charge q2 with charge 8.0x10^-6 C and mass 4.0x10^-9 kg,as shown below.Both charges are positive.Charge q1 remains fixed at the origin,whereas q2 travels to the right upon release.Determine the speed of charge q2 when it reaches a distance of 0.50m from q1,keeping two significant figures.

20.Two electrical poles support a current-carrying wire.The mass of a 2.5m segment of the wire is 0.44kg.A 15 A current travels through the wire.The conventional current is oriented due east,horizontal to Earth's surface.The strength of Earth's magnetic field at the location is 57T and is oriented due north,horizontal to Earth's surface,as shown in the figure below.Determine the magnitude and the direction of the magnetic force on the 2.5m segment of wire,keeping two significant figures for your final result.

If possible,please use type when answering.You can attach pictures if needed.
