    Gravitation(angular deflection of a planet from a massive star)

    i was just thinking , a planet comes close to a very massive star but doesn't collide .how can i calculate the its angular deflection.? i can calculate the velocity afterwards the deflection(given the initial and final perpendicular distances of its course from center of the star) using...

    Hydrostatics - Why is the pressure force the same?

    sorry,but a doubt of my own from here. i know that these 2 containers should weigh different.but shouldn't the contact force be equal to the weight of the body and since the force at the bottom is the same ,shouldn't the weight be same? i think that i might be wrong somewhere but can't figure...

    Finding Forces and Work in a Pulley System

    taikng tensions ,T1=4F and taking constrained motion, acc. of pulling end=4 times acc. of wA differentiating that we get s=4s1 therefore work done by F=Fs work done by T1=T1s1=4F x s/4=Fs correct me if i m wrong,i just tried.

    Need help with Newtons laws. finding normal force.

    N=mg(cosθ) +Fcosθ...(1) Fsinθ=mgsinθ...(2) i.e,F=mg=4.1 x 9.8=40.18 so,F=40.18 from (1),N=mgcosθ +mgcosθ [F=mg] i.e,N=2mgcosθ=2 x 4.1 x 9.8 x cos 45°=56.83 so, N=56.83
