[@nonusingh-gc9pj]

in 8:56 the buoyant force will be 19.6N not 2 kg because buoyant force = weight of water displaced by object . therefore , weight of liquid displaced by object = mg = 2kg * 9.8 = 19.6N. also , the weight of object will be 49N not 5kg because 5kg is mass not weight , weight will be mass * acceleration due to gravity i.e. 5 * 9.8 = 49N .

[@Jamaluddin-alam]

Padhane ka tarika bahut achha hain. Mam ❤ aapka

[@anandkumar1598]

Mam u should notice mass instead of weight because weight is product of mass and acceleration due to gravity

[@amita1642]

Mam.. Aapne kaha ki Weight of the obj. Ke equal hogi bouyant force Bt in application section Weight was 5 kg So why bouyant force is 2 kg ??

[@craziedtimepass6361]

Not weight of the object, it's mass of the object

[@sarvendrakumar9887]

Not the weight of the object the water displaced by the object is equal to buoyant force

[@soumisubhalakshmi5415]

Mam if the weight (force)exerted downwards is equal to the upthrust then why don't they cancel?

[@MagnetBrainsEducation]

Thank you for your question! The weight (force) and the upthrust do cancel each other out, but there is also another force acting on the object - friction. Friction is the force that opposes motion, and in this case it is opposing the upward motion of the object.

[@janhvijain7748]

Maim hamesha Upthrust force waight of obj ke jyada hoga then obj shink krega Or agar kam hua to vo float krega pr Abhi iss case Mai obj ka upthrust force displaced water ke equal hoga...........!!!!

Mam pls ans. My ques

[@vatsalasingh616]

The SI unit of buoyant force is newton.

[@Divyrnneet700plus]

N will be unit for any type of force.

[@ranjusingh6156]

if it does not have a formula then there will be no SI unit i hope you will understand 🙂

[@sharmainstituteofenglish3804]

How do we know the magnitude of buoyant force???plss tell

[@mehroosh]

weight of the object in air - weight of the object in water

[@mindlykindly683]

Weight is supposed to be in Newton... How can you consider kg as a weight???.. Mass is denoted in kg not weight...And same goes for buoyant force.. It should be in Newton as SI unit for any force in Newton(N) and SI unit of weight is also N...so basically there was some conceptual error in the video... 7:25
