A body experiences an upthrust `F_(1)` in river water and `F_(2)` in sea water when dipped up to the same level.
Which is more `F_(1)` or `F_(2)`?Give reason

Text Solution

Verified by Experts

`F_2 gt F_1` since Sea water is denser than river water.

Two small conducting spheres of equal radius have charges + 10 muC and -20 muC respectively and placed at a distance R from each other. They experience force F_(1) . If they are brought in contact and separated to the same distance, they experience force F_(2) . The ratio of F_(1) to F_(2) is

Assertion :- when two non parallel forces F_(1) and F_(2) act on a body. The magnitude of the resultant force acting on the is less than the "sum" of F_(1) and F_(2) Reason :- In a triangle, any side is less then the "sum" of the other two sides.

What happens when F_2 reacts with water?

F_(1) and F_(2) are the two foci of the ellipse (x^(2))/(9) + (y^(2))/(4) = 1. Let P be a point on the ellipse such that |PF_(1) | = 2|PF_(2)| , where F_(1) and F_(2) are the two foci of the ellipse . The area of triangle PF_(1)F_(2) is :
