A20.0kg cart travels at 10.0 m/s in a circle with a radius of 15.0 m. what is the centripetal force? 3.00 n 30.0 n 13.3 n 133 n

Net centripetal force is given by the product of mass and centripetal acceleration

Here we know that

mass (m) = 20 kg

speed (v) = 10 m/s

radius (R) = 15 m

So here we can say that centripetal acceleration is given as

now from the formula of force

so correct answer would be 133 N

iron would move it is magnetic there is a mag field around the current in the wire
