r - How to get expect_equal() function (package testthat) work with rmarkdown files? - Stack Overflow
Two equal circles of radius r intersect such that each passes through the center of the other. The lenght of the common chord is A. sq root of r B. r ×
Two equal point charges A and B are R distance apart.a third point charge placed on the perpendicular distance at a distance d from the centre will experience maximum electrostatic force when?
