Teaching HTET PGT Level 3 - 2024 Mock Test Physics Motion in Two and Three Dimensions Circular motion
If the coefficient of friction between road and tire of a car is 0.15, which of the following expression can be used to find the maximum velocity of a car to avoid any accident on a banked road with the angle of banking θ°
1
\({v_{max}} = \sqrt {rg\tan \theta } \)
2
\({v_{max}} = \sqrt {\frac{{{\bf{rg}}\left( {{{\bf{\mu }}_{\bf{s}}} + \tan {\bf{\theta }}} \right)}}{{\left( {1 - {{\bf{\mu }}_{\bf{s}}}\tan {\bf{\theta }}} \right)}}}\)
3
\({v_{max}} = \sqrt {\frac{{{\bf{rg}}\left( {{{\bf{\mu }}_{\bf{s}}} + \tan {\bf{\theta }}} \right)}}{{\left( {1 + {{\bf{\mu }}_{\bf{s}}}\tan {\bf{\theta }}} \right)}}}\)
