1.	A car is travelling with linear velocity (v) on a circular road of radius (r). If it is increasing its speed at the rate of a (mt//sec^(2)), then the resultant acceleration will be
Answer» `((V^(2))/(r)+a)` `((V^(2))/(r)+a)^(1//2)` `((V^(4))/(r^(2))+a^(2))^(1//2)` `((V^(2))/(r^(2))-a)^(1//2)` Answer :C
