I'm having a lot of trouble with this question. If anyone is getting a different answer than me, then please help me out here.
'The vertical sides of a water glass are each 12cm in length and the diameter of the glass is 5cm. If the water in the glass is 2cm from the top,
through what angle, θ , can the glass be tipped before water spills over the side?'
Every time I work through this I get θ=13.8464˚
The answer key is giving me θ=38.7˚
Either I'm not doing this right or the textbook is wrong, which is entirely possible.
Anyways, help with this would be extremely appreciated.
