8. A Ferris wheel with diameter 18 m and rotates with constant speed of 3.8 ms. Calculate the magnitude and direction of the force which the seat exerted on a 40 kg rider at
the
i. lowest point of the wheel. (Ans: 456.4 N)
ii. highest point of the wheel. (Ans: 328.4 N)

When a neutral charge, comes into contact with a positive charge they repel each other nothing happens the neutral charge becomes negative they attract each other

Could someone . i have tried to solve myself but my calculation is off

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
