Suppose the charge on the second ball is reduced slightly, so that it is less than that on the first ball.
Predict whether the angle that ball 1 makes with the vertical will be greater than, less than, or equal to the angle that ball 2 makes with the vertical. Explain. Sketch your answer above.
How does the free-body diagram for each ball in this case compare to the corresponding free-body diagram that you drew in part a? If the magnitudes or directions of any of the forces change, describe how they change.

Please explain step by step with the complete integrals, in this exercise I do not understand why in X and in Y my teacher gives x=rcosθ y=rsenθ, when the angle in the exercise is θ/2,arrow_forwardPlease indicate the answers to the boxes.arrow_forward
- A small ball of mass m, initially at A, slides on the smooth circular surface ADB (see the figure below) of radius R. When the ball is at the point C, find the force exerted by the surface on the ball? Express your answer in terms of a, m, g and R. A Darrow_forwardA ball is hanging from a long string that is tied to the ceiling of a train car traveling eastward on horizontal tracks. An observer inside the train car sees the ball hang motionless. Part A Draw a clearly labeled free-body diagram for the ball if the train has a uniform velocity. Draw the force vectors with their tails at the dot. (Black vector is the sum of the vectors in my diagram.) Part B Draw a clearly labeled free-body diagram for the ball if the train is speeding up uniformly. Draw the force vectors with their tails at the dot. (Black vector is the sum of the vectors in my diagram.)arrow_forwardChoose the letter of the correct answer A. Statements a and b are both true B. Statements a and b are both false C.

What is the behavior of bits of paper/tissue when brought near to a Comb?arrow_forwardPROBLEM SET # 8: PARTICLE UNDER A NET FORCE On the space provided, present correct and organized solutions to the following answered problems. Box the final answers. Detach each page neatly and submit to your instructor. A 2.5-kg concrete block sliding on a vertical wall is being acted upon by a force P as shown in the figure below. Assume that the coefficient of kinetic friction between the 2. concrete block and the wall is 0.88. 148° (a) Draw the free-body diagram of the concrete block. (b) If the normal force exerted by the wall to the concrete block is 20.0 N, what would be the magnitude of the external force P, and (Ans: 37.74 N) (c) The acceleration of the block?
