Are these answers correct?
These are from Past year JEE mains , but I think they are wrong. Can anyone verify?
For question 7 , bro I am also getting ans. as 15N. But for rocket problem I am getting answer as option 1.I,e: 3.5*10^5
Sorry, for second also answer should be 7*10^5....i forgot to take g on account so I had just blindly put F=ma which is not correct as g is also acting.hence F=m(g+a)...
Correct answes are
15N,7*10^5 and 4.9
In wedge prob, vertical component of acc is gsin^2\theta
g is free fall acc, that's the tricky part here.
Which material is this? @Chirag_Hegde
Seems like there are printing mistakes in ans key
Looks like archive
I think this is the official answer key as many sources online posted the same wrong answers
Don't know abt that
I follow disha's 40 years. It doesn't have any printing mistakes in ans key(at least not yet that i have seen)
Can you cross check these specific questions?
Yeah i checked. What i said in previous post are correct answers there too.
