Centripital acceleration a = v^2/r = 10×10÷12
= 8.33m/s2
Force required to hold the car is F = Ma = 1500×8.33 F =12500 N
Friction force is responsible for this centripital force. If there is no friction then car will start slipping on reaching the curve.
One other force that may be responsible for this centripital force component of gravitational force acting toward center of the curvature only if there is banking of road. If no banking then this force cant come into effect
