+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.So here 1/2* 4* 1.66* 10^-27* v² =2 *9 *10^9 *2 *29 *(1.66 * 10^-19)² *10^13 ?
@.sidd.
1/2mv²=2 k Z e² / r is correct?
Ans is wrong by this idk why
Cuz our sir has given this formula
Is 2 wrong in it?
Even if I remove 2 the ans still is wrong
Our sir said solved it like this and said to simplify this further and ans is correct but its not
Ans is 6.3*10^6 which is far different than what we get from this
i did this
calculation check karo
What ans u got
Approx aaya tha mera
values check karke khud try karo dekho kitna aa raha hai
Isnt this the formula
no
Electron charge squared?
image check kariye usme sahi formula hai
Our chemistry sir taught us this
How is KZ1Z2/R correct
It doesnt have e²
Are u sure this is the formula
Should I ask sir why he gave us some other formula?
Sahi hai
I checked on google.
Sorry hume ye formula padhaya nahi hai to maine galat bata diya.
Kinetic energy will be equal to potential energy
Check whats wrong in this
Values daalo aajayega answer
Photo bhejo I can check
💀 Bro isme samajh nahi aa raha ache se
At very right is 10^13
@Sidd
Ruko mai karke bhejta
Ye calculate it its
805.012 * 10^
Conserve Mechanical Energy of the system
calc theek se karo, you get exactly this
substitute carefully, jaldi me mat karo. i am closing this thread :)
you get v^2 as 4 x 10 ^13, v as 6.3 x 10 ^ 6
