here are solutions

answer 1.....B...he bends inwards in order to balance the torque produced by the friction on the bike

answer 2....A....due to contribution of normal reaction towards centripetal force friction decreases so wear and tear decreases

answer3...B....contact force is equal to mg till angle of inclination is less than tan inverse u...uptil theta equal to tan inverse u the normal rxn decreases but at the same time friction increases so total contact force is constant that is mg.....after that sliding starts and friction and normal rxn both decrease

answer 4...1218 newtons...let T is the tension in the rope...acc. of man wrt ground is (5g/4-a) where a is acc. of rope....writing eqns of motion.......T-100g=100a and T-60g=60(5g/4-a).....solving the two eqns we get T=1218 N

answer 5...a) p,q
b) p,r
c) p,r
d) r,s
( if anyone wants explanation of match the columns please nudge me)


answer 6...abc...friction.tension,normal rxn are electromagnetic forces if seen at microscopic level

I dont stick to chair when I sit on it.
I sit on the chair becoz it comes in the way of gravitational force pulling me down and it gives a reation to me.
Reaction doesn't stick 2 masses.
