The friction of the air causes a vertical retardation equal to 10% of the acceleration due to gravity `(take g=10ms^(-2))` The maximum height will be decreased by:

The friction of the air causes a vertical retardation equal to 10% of the acceleration due to gravity. Take g=10 m//s^(2) the maximum height and time to reach the maximum height will be decreased by

If the friction of air causes a vertical retardation equal to 10% of the acceleration due to gravity then the maximum height and time to reach the maximum height will be decreased by (g = 10ms^(-2))

Acceleration the due to gravity become [(g)/(2)] at a height equal to

If radius of earth decreases by 10%, then acceleration due to gravity (Density of earth remain constant)

If radius of earth decreases by 10%, then acceleration due to gravity (Density of earth remain constant)

If retardation produced by air resistances to projectile is one-tenth of acceleration due to gravity, the time to reach maximum height approximately-
