@thushananth01 Plzz Procede
give me a min
OK
x = \[45^{o}\]
hw
|dw:1343894414685:dw| mgsinx=1Ncosx g=10m/s
ok.......... This is a multiple choice correct answer there is one more option which is correct..
x=45

friction?
x = 45 x > 45 and friction acts towards p x > 45 and friction acts towards Q x < 45 and friction acts towards Q
If I take g=10. sinx = cosx only when x=45.
ok.....1 st opt ion is correct .......i1 more we want
If g=9.8. sinx < cos x. So to make it stationary I would need friction towards P.
okay. so g must be 10. other option should be the third one. if x>45. sinx>cosx. and for block to be stationary we need friction towards Q.
@Ishaan94 in the question it is said that g =10m/s^2 i forgot to mention
if g =10 m/s^{2} then there is no friction because it arises when there is any tendency of motion. but at x =\[45^{o}\] the net force is zero.
thxxx
m*g*sin(x)= 1* cos (x)substituting the value of m and g will give x= 45
