:D :D its amazing the above conversation is making sense :') the curved path thingy

Beautiful simply beautiful sensei the effort is much appreciated I can finally see what's happening here :') which made this thing much more simple:)

Are u referring ti.something like this?

But I think I dnt understand the question properly. .. if the fleas walk in a straight line and its a square cube how do they meet at the center thy must just walk 1 inch... how will they meeet ( this is getting confusing:( )

This was the question ..... Yeah my teacher told me the path willl be curved today I know why thanks to u and special thanks for answering such a stupid question ...

In case 1 the electron moves In a straight line In case two the field lines are shorter at the bottom than at the top Force on electron is towards right the field lines also go from positive to negative I.e towards right .... but the electron is negative hence repels .. (therefore not sure about the path of electron.... it will depend on the fact which is stronger the p.d or the repulsive force by electron) maybe . Foxy john if I were the elctron I would have chose to go.from the bottom ... lesser distance less time

I have a theory question this time ... case 1 if I have two plates and theres a potential difference (p.d) across them 250 v ... an electron is fired from one end to the other end with some speed v m/s Case 2 Now I take the same plates same p.d however the plates are not uniform this time..... willl this have any effect on the speed of the electron? Compared to case 1 ... or will the time change?

Yessssss! !! :D

My working is beneath question

Hmn so the potential energy at thestart of motion convert to kinetic energy (ke ) the ke is max at the bottom when ball is about to hit the groud so the potential energy at the begning converted to k.e Now since the balll after rebound didnt go back to 80 cm some energy must have been lost as heat light .. But in the upwards motion to the k.e getconverted potential energy. Thats all I know about k.e and g.e

I am literally clueless about this question.. the only thing I understand is the rate at which motor works implies power . And its rising at steady speed .so maybe the kinematic eq will come in handy.... how do I get started

Okay okay ojaay maybe we take the height as 80 -8 cm.... bcz we start the height frm center of gravity of baallll and end it at COG which makes a complete diameter

Diameter 8 cm .. 0.08 m

Oh so il take the height as .8-0.04 meters .... Then the p.e will be mass× -9.81 × .8-0.04 ?

I used the kinematic equations To first find mass from the k.e given And in the secound part I used the mass to calculate the new k.e .... I attached my working
