Shut up leon

hell yea grammar (Y)

Ah I see now ty. FML 11/15....

Waahhh. Nothing moved though.. It's just that there is earth between the sun and moon isn't it...

5 is c. By the formula for gravitational attraction the earth doesn't affect the force. The distance between the sun and moon is still the same

Wait sorry I realise now it's b FML...12/15

Force changes with time so it can't be b.....and it's not based on the current. It's based on the coil itself which is initially parallel to the field so theta=0 . Therefore initial force is 0

Force changes with time so it can't be b.....

11 is D sin0=0 so force is minimum as theta increases, force increases it is not constant till 90 degrees sin90=1 so force is maximum cos0=1 so initially torque is maximum cos90=0 so torque is minimum so its D QED

A=v^2/r*

for question 2 u jet we to do the centripeal acceleration formula A=v^2/. Where r isthe radius

Can someone put them up?

I thought it was easy and relatively straight forward. Particularly since the questions in indochina and Germany came up In our trial( grammar) :D

60-62/84???

cant really judge the difficulty of an exam over one binomial question xD
