An electron of mass 9.11×10−31 kg leaves one end of a tv picture tube with zero initial speed and travels in a straight line to the accelerating grid, which is a distance 2.20 cm away. it reaches the grid with a speed of 2.70×106 m/s . the accelerating force is constant.

Explanation:

We have given that mass of electron

It is given that initial velocity u=0 m/sec

Final velocity v =

Distance S = 2.2 cm = 0.022 m

According to third law of motion

Accelerating force F is given by F = ma

So accelerating force

the body's situation won't change the forces are equal opposit and on the same body

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
