An electron with speed of 104 m/s enters a ""forbidden"" region where an electric force tries to push it back along its path with a constant acceleration of 107 m/s2 . how far will the electron go into the ""forbidden"" region? how long will it be in that region?

Part a)

Part b)

Explanation:

Part a)

The electron will move in this forbidden region till its speed will become zero

So here we will have

also its deceleration is given as

so we will have

Part b)

Now the time till its speed is zero

so total time that it will be in the region is given as

the answer is d. 4

hope this

also the more points you give the faster your questions get answered
