g' = g( 1-d/R )
Now d that is depth is R/2
substituting d
g' = g(1-R/2R )
g' = g/2
multiplying both sides by m
mg' = mg/2
weight is nothing but mass * gravity
Weight at halfway depth = W/2
Now d that is depth is R/2
substituting d
g' = g(1-R/2R )
g' = g/2
multiplying both sides by m
mg' = mg/2
weight is nothing but mass * gravity
Weight at halfway depth = W/2
