no way you will lose alot of marks. I say youd gain marks for implying the rule for friction. One of the two equations you set is correct but the other is wrong so something like 4/7
(Btw you are one the few people who got 5.20 and think they are were wrong... Do you know what went wrong for you? Thanks)
I seriously don't know what did. I can explain you the way I did it though. I solved the problem by simply taking the direction of P acting up the line of greatest slope for 1 case and down the slope for the other one. Also changed the directions of friction. Made 2 simultaneous equations multiplied the smaller one with 2 and then just solved it. Thanks for the opinion though!
