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.there is pi in value of mewnot and pi in area of solenoid now that will become pi squared and it is a good approximation in physics to take pi square = 10 so maybe thats what they did
The answer is 4x 10^-2 even after putting pi^2=10 im not getting this🤔
thats only possible if radius 1 m
It is given as 1cm
Here @Gamertug
i think ans might be wrong
Alright
+solved @Gamertug
