How is the focal length of a spherical mirror related to its radius of curvature?

Text Solution

Verified by Experts

The radius of curvature, `r=(v^(2))/(gostheta_(0))`
`theta_(0)`=angle between v & horizontal = 0, when the ball is released. It starts moving horizontally with a speed y = speed of the train `10 m//sec`.
`rArr r=(v^(2))/(gcostheta^(@))=((10)^(2))/(g)=10m`
`thetA_(0)`=angle between V & horizontal = 0
