apply the concept of pseudo force for this one. to keep the body stationary you need to balance the force acting downwards on the body which is equal to mgsin theta. so try this one yourself :) so gsin 30 = acos 30 ( angle b/w and and normal is 60 ) so you’ll get the answer :)

Hello Ananya,
 
Please type the question completely and not in the form of image else it will not be useful for those students who will be searching question of this type on google. However, you can attach diagrams of the question, if any.
 
@Neeti, try to post answer of different users so that other students can also get benefit from your knowledge. Giving answers to one user only is not good practice on forum. You can answer as many questions of Ananya as possible alongwith other users. This is clearly written in terms and conditions of forum policy as well which can be seen by clicking on the link given below:
 
Hope that you all will follow forum guidleines
 
Thanks
