A baseball is hit high and far. Which of the following statements is true? At the highest point,
erma4kov [3.2K]

Answer:

option C

Explanation:

When the baseball is hit high and far it has some horizontal velocity at the highest point so option an i.e. velocity at the highest point is eliminated.

the baseball act as a projectile at the highest point so, there is always downward acceleration acting on the body. so, option e and d is eliminated.

At the highest point, the vertical velocity is zero and neglecting the air resistance we can say that the velocity of the body is slowest.

Hence, the correct answer is option C

A charged particle moves at 2.5 × 104 m/s at an angle of 25° to a magnetic field that has a field strength of 8.1 × 10–2 T. If t
nekit [7.7K]

the magnitude of charge=q=8.76 x 10⁻⁵C

Explanation:

the magnetic force Fm is given by

Fm= q V B sinθ

q= charge

v= velocity= 2.5 x 10⁴ m/s

B= magnetic field strength= 8.1 x 10⁻²T

Fm= magnetic force= 7.5 x 10⁻² N

θ=25°

so 7.5 x 10⁻² =q (2.5 x 10⁴ ) (8.1 x 10⁻²) sin25

q=8.76 x 10⁻⁵C
