Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Why isn't energy conservation working
Collision means you have to apply the angle condition right?
Your equation is right. It gives you the final velocity in the y direction (along field basically)
final velocity toh zero hui na
? Kaise?
we have to provide just enough velocity to let the electron move against the electric field between the plates and escape after covering vertical distance d1
tell me why it shouldnt be zero
That's v_x minimum to be precise.
Because I put in the boundary condition
Also, don't mind the handwriting
given ans is twice of yours
this half is not needed
also the electron is projected midway so d1/2 instead of d1
i got the ans this way too but wanted to explore energy conservation method
how to do using COME
Mb yeah
..
Anyone ...?
Hmm energy conservation should work here
Lemme see
Velocity nikal lo net na
Y direction ki bhi velocity aaegi
And x mein to hai hi
Baaki to Sahi lag rha h mujhe
🤔
o bc dono dirn mein to conserve hi ni ki
will try again
wdym
idk what i just said
u gave weekly?
na bhai
how much did u get
i heard maths mein printing error tha and chem ka ans likha hua tha ek
haan in 2 ques
maths me
93 💀
messed up in maths 😭
93 is big W dude
COME wont work since initial velocity is along x axis . since theres no accn along x axis it will remain same . all the change in potential energy will go towards increasing velocity in y axis is of no use to me right ? @Opt
you would have to eqeate e(change in V) = 1/2m(velocity in y axis at end of plate)...and this velocity would have to be accn*t and t would have to be calc from vel in x axis, a ...which would be similar to whats done above
yeahh
+solved @Opt

Sorry, but yeah, basically. I just saw the message 🤦♂️
