hint find radius of curvature formula then balance forces..
@Sneha_2021 I have problem with sign only. One solving I am getting both sign. please provide a proper reason to neglate negative sign
- you can only get in roc calculation as you have to find vmax will be always positive nthing sophisticated..
- for more instance draw graph you will see velocity always along postive x direction at highest point of curve its irodov problem...
@Ankith_2020 move with -ve velocity of same magnitude will be equivalent to move on path -a sin( x/ alpha) so there shouldn’t be any problem i think .
From where did you get this question ?
Thanks @Shwetanshu_2018 I got it. This from a mock test (embibe).
