Find the time constant of the circuit

[Fatima Hasan]

Homework Statement

In the circuit shown S is closed at t = 0 . Find the time constant (in s) if C = 2μF.

Homework Equations

τ = R_eq C

The Attempt at a Solution

R = $\frac{10*10}{10+10}$
R = 5MΩ
τ = 5*10⁶ * 2*10^-6
= 10 s
Could somebody check my answer?
