This note is concerned with everyone on brilliant . I have been solving problems in Mechanics section which are sometimes ambiguous or their answer is not correct. For an instance , this problem. The answer has been rounded off without informing. There are times when value of acceleration due to gravity isn't mentioned and what u use is different from the one used in answer (it has happened to me with both 10 and 9.8).I even reported the problems but there was no reply from brilliant. This results in unnecessary decrease in ratings!I request the staff to look into the matter.
