Pseudo ForceMediumQuestion 30215

Question

A pendulum hangs in an accelerating elevator (acceleration a upward). The apparent tension in the string is:
  1. A
    mg
  2. B
    m(g−a)
  3. C
    m(g+a)
    Correct
  4. D
    ma

Correct answer

m(g+a)

Explanation

In the ground frame, T − mg = ma (net upward force). So T = m(g+a).
