Two-wheeler can tilt while turning, but four-wheeler cannot. Estimate maximum safe
\( \mathrm{P} \) speed of a four-wheeler on turn of radius
W \( 10 \mathrm{~m} \) assuming coefficient of static friction between tires and the flat road to be \( 0.64 \) and acceleration due to gravity to be \( 10 \mathrm{~m} / \mathrm{s}^{2} \).
(1) \( 6.4 \mathrm{~m} / \mathrm{s} \)
(2) \( 2.8 \mathrm{~m} / \mathrm{s} \)
(3) \( 8 \mathrm{~m} / \mathrm{s} \)
(4) \( 10 \mathrm{~m} / \mathrm{s} \)
