An electron is released from rest at a distance d = 100 m from an infinite conducting plane. the electron will begin to move towards the plane due to charge induction in the plane. how long will take for the electron to strike the plane?

t=89.44 sec

Explanation:

Given that

d= 100 m

Mass of electron

Force acting on electron

Now by putting the values of K and charge on electron

As we know that

F= m a

So acceleration of electron

a=F/m

We know that

here electron move from rest so u= 0

t=89.44 sec

So time taken by electron is 89.44 sec.

their crystal patterns have been disrupted by stress

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2
